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();

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?

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.
