Top Forums Programming What is an "Illegal Instruction -Core Dumped" Post 39084 by Perderabo on Wednesday 6th of August 2003 10:08:38 AM

Your process is dying because it recieved a SIGILL. If that came from the kernel, it means your process tried to execute an illegal instruction.

I don't use debuggers, so I cannot comment on that "noname". But you would appear to have a bug in your code.

My best guess is that you overran an automatic array and clobbered a return address on the stack. Later, a return statement will take a flying leap rather than returning to a caller.
