openal causes SIGSEGV on "crash"

[kortemik]

... entered "developer 1" and "crash" on the console:

Program received signal SIGILL, Illegal instruction.
BFG::crash_f (args=...) at /home/kordex/code/OpenTechBFG/neo/framework/Common.cpp:633
633     __builtin_trap();

as expected. But later:

soundSystem->Shutdown();

AL lib: (WW) FreeDevice: (0x39e7d90) Deleting 3 Buffer(s)

So you're surprised that the game crashes when you crash it? And that one crash gets it into a flakey state so other crashes follow later? ...

[kortemik]

I am not surprised by that, it should come down cleanly as the sig_handler is bringging the live engine down. sigill is being handled and because of that it should come down as cleanly as with sigquit. openal seems to skip some checks.

it wont happen on rbdoom3 as their assets have sounds playing from startmenu onwards we don't have that.
