This test case silently returns the wrong answer

Following up on a 'grep' bug report here:

https://debbugs.gnu.org/29613

attached is a seemingly-related test case which illustrates a bug that causes 'grep' to quietly return the wrong answer instead of dumping core. This test case should exit successfully, but because of the bug regexec returns 0 so the test case exits with status 1. I compiled and ran it on Fedora 27 x86-64 with "gcc regbug.c; ./a.out".
