The shell script attempts to suppress core dumps like this:
old_ulimit=$(ulimit -c)
ulimit -c 0
$QEMU_IO arg...
ulimit -c "$old_ulimit"
This breaks the test hard unless the limit was zero to begin with!
ulimit sets both hard and soft limit by default, and (re-)raising the
hard limit requires privileges. Broken since it was added in commit
dc68afe.
Could be fixed by adding -S to set only the soft limit, but I'm not
sure how portable that is in practice. Simply do it in a subshell
instead, like this:
(ulimit -c 0; exec $QEMU_IO arg...)
