OS Verison: Windows NT 4.0 SP6

I have encountered this problem only in the latest version of regex,
It appears that the regex package does not like legal statements! Did
you get this change from FSF? ;-).. The 1.7.1 development released
version does not exhibit this problem. The current file version of
regex.c I am using is 1.47 and the version that was working correctly
was 1.41.

When I run the attached script it seg faults after 45 iterations in
the following location:
