Yes, but unfortunately I can't reproduce most of those exit 3 failures
locally. Here are a list of programs that fail with code 3 in nightly
builds...
22.locale.codecvt.length
22.locale.codecvt.out
22.locale.ctype.is
22.locale.ctype.scan
22.locale.ctype.tolower
22.locale.ctype.toupper
22.locale.ctype
22.locale.moneypunct.mt
22.locale.time.get.mt
22.locale.time.get
22.locale.time.put
I see no problem if I run these executables, either by themselves or
under the exec utility...

So I'm stumped how this exit code 3 thing can be coming up if the
program itself returns 0, and the exec utility correctly detects the
return code.
Also, just as an aside, the exec utility function kill_child_process()
can call TerminateProcess() with exit code 3 if sending ctrl+c and
ctrl+break don't kill the process first.
/* Then hard kill the child process */
if (0 == TerminateProcess (child.hProcess, 3))
warn_last_error ("Terminating child process");
else if (WAIT_FAILED == WaitForSingleObject (child.hProcess, 1000))
warn_last_error ("Waiting for child process");
Are you able to reproduce the exit code 3, or at least a debug dialog
for any of the above mentioned tests?
