FYI, the reason why you can't grep for "Illegal Instruction" (or 
"Segmentation fault" or other such error messages), is because 
that is printed by the shell running your test shell script, i.e. 
it happens "above" the grep command. (Specifically it prints this 
message as a result of the process being killed by SIGILL / 
SIGSEGV etc.)
