Patch for bad pointer / leak in regex_internal.c

regex_internal.c mistreats malloc failures in a couple of places. In one, it
dereferences the resulting NULL pointer; in the other, it leaks another block
of memory when an malloc fails. The latter problem was found by Coverity.
Proposed patch attached.
