Summary0003184: SIGFPE in OpenAL when eaxreverb is enabled
DescriptionSpring 89.0 with ALSA + Openal Soft crashes at launch screen unless you disable eaxreverb in ~/alsoftrc

Not sure if this only affects ALSA.

Attached info about HW + infolog. I compiled libopenal.so with debug symbols (-g3) but for some reason I can't get spring or GDB to show relevant function names in the stacktrace.
Steps To ReproduceRun Spring from commandline. On affected hardware you will get a crash at the launcher screen.

If you disable eaxreverb you don't get a crash.

cat ~/.alsoftrc

[general]
drivers = alsa
excludefx=eaxreverb # this line will prevent crash

Forgot to mention that UseEFX=0 has no effect on this issue.

 You compiled spring with DEBUG2, spring will not crash with RELEASE, neither is it a crash it is an dev-important-only error

 thats afaik SIGNAN=TRUE, not debug. (signan is disabled as default)


hmm, wouldn't it make sense to not stop the engine on SIGFPE? (the stacktrace would/could help enough)

Confirmed. Building release 89.0 through portage as normal doesn't show this issue.
