Interesting. If you're exceeding your stack ulimit, you should be seeing either an "argument list too long" message or getting a SIGSEGV. Have you tried bypassing wc and piping the output straight to a file?I think it sends SIGKILL on failure paths.Setting stack limit to unlimited I managed to exec with 10MB, and "wc" produced the correct output when it (finally) ran, so no odd limits being hit in there.
Ah, good :-)
Ah ... running the 34*100K case direct from my shell prompt, I do see a "Killed" that must get lost when I run this in the shell script loop.
Yes, so it seems we just trip the stack limit after we cross the point of no return. I started looking into growing the stack beforehand and perhaps shrinking the stack after we're done. That would get most if not all these failures before the point of no return.
