What is not consistent is that it's taking I/O/cache/VM activity
(caused by grep) to trigger the crash. I left the binary ran in an
infinite loop for a few minutes before launching grep and everything
was fine. The message was printed without trouble and the binary ran
finely too. As gcc was called without argument, it completed almost
instantly. If that was as trivial as a bad call to printf, it would
have failed on the first pass, doesn't it ?
