Fix a bug which goes unnoticed on all platforms but leads to a
coredump on FreeBSD/amd64 when one uses $^N variable and there were
no captures in the last executed regexp.
One third of this fix was applied to the perl tree in December 2002,
with the rest hopefully applied in the next couple of days.
