Originally created by @LewisR on GitHub (May 15, 2020).

Unfortunately, when attempting to start the last Firefox build submitted to AN (firefox-45.9.0-2), the exe exits immediately, with no TRP file. Downgrading 9.2.0-4 (or 9.2.0-3) gcc packages to 9.2.0-2 allows the program to start. I have installed libc-debuginfo, firefox-debug, gcc-debuginfo. Luckily, this package was not widely distributed, However, it is unknown what other applications may be similarly affected with the new gcc build.

I'm happy to try to get some useful data out of this, but right now, all I get is a quick program exit (almost immediately). The TRP file (with exceptq=Z) is a standard process termination notice, and as exceptq traps, it's hard to know what may be useful.

Edit2: Confirming my original findings. 9.2.0-3 does not work, either. Attempting (again) to gather debug info.
