This means the program has crashed due to Illegal Memory Access
it could mean
1) you're running a binary that wasn't compiled on your system which
is calling calling libraries with different APIs than what you have
installed (or for that matter multiple versions of the lib may exist)
2) The program and are doing something bad to someone elses
memory
i.e.
...
char test[5];
for (i=0;i<300;i++)
test = 0;
Think of it as a loose translation of General Protection Fault
