Hi all,
From time to time my program crashes with exit code -4. I
can't seem to find much on the code. Does anyone know what
this means and how to debug the issue?
Unix signal #4 is illegal instruction (negative returns usually
mean it was killed by that number signal). Most common way to
hit that is a broken function pointer or corrupted class
leading into data that isn't supposed to be executed as code.
Also possible an assert(0) got hit in release mode or something
like that.
Easiest way to debug it is to open it in a debugger and look at
the stack trace to see where it came from.
Oh, so it's just signal 4, not -4?
