I'm reassigning this to the SDL package for now, but it might be
libasound2 that is at fault.

A short summary for the SDL maintainers:

simutrans crashes on Claudio's system in the
SDL_InitSubSystem(SDL_INIT_AUDIO) call.  So does a simple test program
that just calls this function and nothing else (it works on my system).

Note that several libraries (libc6, libgcc1, libstdc++6) on Claudio's
system come from experimental.  I don't know whether the crash only
occurs with those or not.

Ansgar
