If you can stand the performance hit, compile PCRE to use the heap
instead of the stack. Even so, you may find you run out of heap with
pathological patterns that recurse and recurse and recurse.
Alternatively, investigate the PCRE facilities for controlling the depth
of recursion (grep the docs for MATCH_LIMIT).
