>Organization:
>Environment:
Linux RedHat v7.2
>Description:
Compiling the attached source at optimisation level 3
results in a core dump 100% of the time.  Regular compile,
or compiling at -O2 never core dumps.
>How-To-Repeat:
gcc -O3 filler.c
strip a.out
./a.out > file.txt
Aborted (core dumped)
>Fix:
Don't compile using -O3.  ;-)
