I can guess there are two reasons you may not receive a reply from the sole developer of this application:
- You are using an unsupported OS.
- You did not provide a backtrace with symbols.
A backtrace might be useful information for your posted issue on Github -- the developer might be willing to review it, even though this is an unsupported OS.
OpenBSD has gdb(1) 6.3 built-in, and there is also a port/package of gdb 7.2, ("egdb") which may be useful for applications built with gcc 4.9 ("egcc") such as this one.
