Hello,
I've just ported lua to an IBM mainframe, z/OS system. All was cool
until I optimized and now I am getting segmentation faults. I'm
wondering if this is a build problem or a nasty bug.
Find below the stack trace. The problem is due to strlen() failing
due to a bad address which is 0x7fff0100. Unfortunately when I
compile with debug it goes away.
Traceback:
