Please forgive my ignorance. Here is the backtrace https://pastebin.com/3k0agGeg

When it crashes in gdb, you want to run `backtrace`, not `kill`. Then paste the output that appears in the terminal window.

Thanks. However the backtrace is truncated. You need to keep hitting the return key to show more, and paste the whole thing. :)

Also it looks like you're missing debug symbols. See the following document to learn how to generate useful backtraces on Gentoo: https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces

Yes I have re-emerged elisa with USE="debug", added CFLAG/CXXFLAG="-ggdb" and FEATURE="nostrip"

The elisa binary increase from 931K to 2.6M so I belive its not stripped. However the backtrace seems to be the same as before. https://pastebin.com/3bba1m7q

Please let me know if I can try anything else.

I can ensure im not missing debug symblos anymore. Ive dumped everything I can think of from gdb into this huge 14M .txt file https://gofile.io/d/lkvYNt

If this does not suffice please close the issue. Im not sure what else I can do.

Best Regards,
Mitch
Comment 8 Nate Graham 2021-01-19 16:53:06 UTC 
Yeah looks like you still don't have debug symbols. You might want to ask fellow Gentoo users how to get this working.

Im sure theyre there...

For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from /usr/bin/elisa...
Reading symbols from /usr/lib/debug//usr/bin/elisa.debug...
(gdb)

Its just odd because the backtrace looks the same as before I compiled with them.
Comment 10 Nate Graham 2021-01-20 17:29:38 UTC 
Hmm, well the problem seems to be that the crash is entirely in Qt. So you have Elisa debug symbols, but it's not crashing in any Elisa code.

I guess if you want to install Qt debug symbols you can report this to Qt, but TBH it would probably be a waste of time due to the situation with Qt 5.15.x right now. :/

Sorry.
