Segmentation fault in FitzQuake SDL 0.80 with Ubuntu

I'm having a weird segmentation fault in FitzQuake SDL 0.80 with Ubuntu. I have compiled it myself using scons, instead of using the provided Code::Blocks project. Maybe i missed something? GDB says:

Program terminated with signal 11, Segmentation fault.
#0 0x00007f31fc715996 in ?? () from /lib/x86_64-linux-gnu/libc.so.6

Update: Changed -O3 to -O2 and added -Wall. Now i get a different output from GDB:

Program terminated with signal 11, Segmentation fault.

I'd download Quakespasm and compile that on your target and see if it works if self-compiled in CodeBlocks.

At least before compiling FitzQuake 0.80 SDL.

FitzQuake 0.80 is, to the best of my knowledge, pre-64 bit. Unlike Quakespasm.

Then if Quakespasm worked fine, you could look at the Quakespasm CodeBlocks project settings and options and fix your FitzQuake 0.80.

(Quakespasm is basically FitzQuake 0.80 that has been actively developed and improved).

Yeah, that's it. QuakeSpasm works perfectly, same scons build script. I'll mess around in the 64 bit changes they made.

0.85 actually

Don't use Fitzquake SDL 0.80 for anything - it never really made it out of beta and was superseded by QuakeSpasm.
