izard#!/bin/bash
if crashes.x >/dev/null 2>&1 | exit $? ;
then
echo Not crashed
else
echo Crashed
fi
if crashes.x SIGSEGVs, the script above sometimes prints "Not crashed", and sometimes "Crashed". (I need a pipe hack because simply redirecting to null does not prevent error message on a console).
Strange, where this non-determinism could come from?
