I was just bitten by this bug as well, patched it, then found this bug
report. For reference, this is the patch I'm using locally, using the
documented instruction in wait(2) to only call WEXITSTATUS() if
WIFEXITED() is true. Please count this as another request to put a
warning in the manpage until it is resolved. Thanks.
