Programs dumping core

[unicyclist]

I upgraded to 6.4 snapshop (amd64) and now lots of programs are dumping core, including chromium and xfce4. I had to switch to icewm because xfce was so bad, but now running FreeBSD till solved.
I've searched trying to find answer and it seems the problems may be related to "pledge".
Is there a sysctl adjustment I can make?
I don't know what info I can provide can be useful. 6.4 boots fine, just when I start using X, then I get a bunch of core files in home directory.
I am using my Dell Inspiron 15 with 4 gig ram and never had this problem.

Thanks for help

I will make a guess.

• Did you decide not to upgrade/update your third party packages? If so, update them with:
  
  # pkg_add -u
  
  There was a major change when amd64 transitioned from gcc to clang in June.

If that fails to solve the problem .... Those core dumps contain the reason for application failures. gdb(1) or devel/gdb may be of some assistance if you'd like to do some debugging or root cause analysis.

[unicyclist]

jggimi, yes I did. In fact just botted into OpenBSD to make sure. Did upgrade again, and couple of files upgraded...something fonts.
Here is the ouput of gddb chrome.core:

There is absolutely no warranty for GDB.  Type "show warranty" for details.
This GDB was configured as "amd64-unknown-openbsd6.4"..."/home/mike/chrome.core": not in executable format: File format not recognized

[jggimi]

gdb(1) has a lot of options, The most common syntax for obtaining backtraces from core files is "$ gdb path/to/program.file path/to/core.file"

This is why gdb() complained that the first and only operand you provided was "...not in executable format" -- it was not a file containing a compiled binary program.

Try something like $ gdb /usr/local/chrome/chrome chrome.core

If successful, you should learn the cause for the failure, and be able to request a backtrace at a gdb> prompt with "bt".

The only packages which contain symbol tables are libraries. So package backtraces will be fairly empty of detail, but they should name the modules called in order (as long as the stack was undamaged) and the core file should note the reason for the failure.

[unicyclist]

Ok, thanks jggimi. Sorry, I had deleted the core to make chromium run. I just started over and this time it didn't dump a core.
Now that I know how to use gdb, I'll keep trying to start chrome and will post output here as soon as I get another one.

[unicyclist]

I started X again with xfce4. Chrome loaded, but I did get a xfsettingsd.core.
Couldn't capture all the output of gdb, but here is first and last section of it. Otherwise, it was showing a lot lines showing the symbol word

Core was generated by `xfsettingsd'.
Program terminated with signal 10, Bus error.

[jggimi]

The gdb() program reported that the program was halted and the core was generated due to a bus error. As I noted above, only package libraries are built with symbol tables, such as the gio library noted in your output.

#0 is the top and therefore last backtrace entry. #1, if present, would be the next-to-last entry, and so on.

The script(1) tool can be helpful to capturing a console or xterm session. Its output file captures control sequences also, so it is best to post-process the output through col(1) with the -b option for readability.

Edited to add: that you are seeing symbols (such as source code module and line number) in backtrace #0, indicates that this is library code.

[unicyclist]

Thank you jggimi. I appreciate your help.

I have some homework to do on script and col
When I get familiar with them, I will post output of gdb again.

[unicyclist]

ok, hope this helps, and yes, you are correct. Appears to be library problem

What follows is output of a chrome.core. Again, libraries.
I am considering a fresh install since something is very amiss. The led for the harddrive was constantly lit so I checked top to see what might be going on, and found that the ld command ran for a couple of minutes nonstop. With these library problems, I'm wondering if something didn't get upgraded properly. OpenBSD has been on this laptop for quite some time. I have a separate /home, so no problem starting over. Just back up /etc and ls of /var/db/pkg.
ok, head of dmesg:

[jggimi]

I don't think I'll be much more help. I'm no programmer. There is one more operational step you could take, which is to run pkg_check(8). If the problem is caused by something in /usr/local which should not be there, or some other damage or leftover cruft is getting in the way of proper operation, this may cure it.

If not, and if no one else jumps in, you could post an informal problem report to misc@. And of course, if you don't mind reinstalling, that will likely be a useful solution.

All that I can determine is that:

• The chrome error shows a problem in libc, called through libX11. You're on the correct major/minor of both. The failing library call was to _fmt, which stopped the program due to a missing variable. The call came from libc's wcsftime.c module, last updated in 2015.
• The xfsettingsd error shows a problem with the address values passed to devel/glib2, in its gio functions. You appear to have the correct version of both libglib and libgio, too.

Thank you for all your help jggimi.
I'm going to start with fresh snapshot install. No big deal for me to start over. Rather do that than to bother more people. You helped me tremendously and I learned quite a bit from you.
Then I will see if something was broke on this system/upgrade as compared to new install.

Will post again after installation complete, but won't have everything done till tomorrow (local time).

I am marking this one solved. I did do a fresh install of 6.4-beta and now all is well.
I am back to running this system.
Thank you very much gjjimi for you help, and the things you mentioned that helped me very much in learning how to do things Very much appreciated.
