I'm using SDL with X.

I ran my program in gdb several times and backtraces shows me that crashes 
happens in two different places, but always in free() or malloc() calls 
performed from different libs (Lua and OpenAL). This *only* happens if I'm 
reading from stdin in my program's main loop, no matter where exactly :-( I'm 
still trying to find out the reason of such strange behaviour...
