I'm doing some production on my machine. I think I should stick to the -stable branch.

notooth: a private message was sent to you 12 hours ago. When you have an opportunity, please download and install the transmission package. You do not need to trust it and run it, but it can be used with your saved .core file: addresses will be converted to source code line numbers, and we can learn the value of any variable or any data structure stored in memory at the time of the abort.

The only variables we would not be able to discern would be variables that were stored in CPU registers through compiler optimization. If needed, I can build transmission with optimization disabled, but in that case you would need to run the non-optimized application and obtain a new .core file.

Hi jggimi,

I have installed and run the transmission-gtk from you without crashing. At the moment I installed the new transmission-gtk, firefox still crashed. I've just removed and reinstalled firefox, and it is currently running smoothly. The firefox-esr which is not reinstalled still crashes.

[jggimi]

If you still have your transmission-gtk.core file, you should be able to obtain a backtrace with symbols: transmission-gtk source code line numbers.

With that information, we can examine the source code, then through gdb request the value of variables or other applicable data structures, and determine what transmission was requesting of GTK and why. We can then follow the stack trace forward, function by function, and perhaps determine the problem source.

Or not. But we won't know until you've been able to apply the symbols to your .core file successfully.

Here is the backtrace that I've just made:

[jggimi]

This particular core file does not have a complete stack trace available. Frame #12 was overlaid with zeros, and the backtrace ends prematurely, before reaching the transmission application.

This appears to be the first time a problem has repeated. To me, it appears to be the same problem reported 3 days ago here, with the same lock pointer, overlaid with the same invalid data: 0xDF repeated.

The repetitive nature of this problem is actually good news. It means it is less likely to be hardware, and more likely to be software.

Excellent! We're in main.c, initializing the application. Let me go through the source code once I'm done with $DAYJOB, and we'll see if we can figure out what is happening.

[jggimi]

In transmission 2.84 source code, the main() function starts at line 613 of gtk/main.c, so we are only in the initialization routines of the application when transmission makes the GTK library call in frame #8. Line 689 of the file states:

ret = g_application_run (G_APPLICATION (app), argc, argv);

This runs a GTK application, and is documented here. The argument management variables argc and argv are standard command line argument count and argument array, and if transmission-gtk is started without arguments on the command line, argc will be the value 1 and argv[0] will be the executable path name.

From that point onward, the stack trace leaves transmission and does not return.

I'll try stepping through the application here, on a -release system, and see if I can determine where the stack path diverges.

[jggimi]

Due to GTK thread management, I'm having a difficult time with live application analysis via gdb. I'm going to recommend sending me the .core file for analysis, if you'd like additional debugging.

My assumption is that since the application failed early in use, there is no personal or private information in process memory, but I'll leave that to your decision.

If you decide to send a .core file, I'll create an account for you that you can use to transfer the file to me via sftp(1), without having to use passwords. You'll create a public/private key pair, and send the public key to me. Only someone with the private key will be able to log in.

I'll send details via private message.
