Comment (by rhaas):

 I updated the patch to output a ALERT level warning in the routines
 calling RegexMatch. It's actualy rather hard to actually trigger it though
 right now. The only callers of RegexMatc hare the routines that validate
 parameter ranges. Since the perl configuration scripts already check
 regular expressions for correctness one has to construct a valid perl
 regex that fails in C (the perl extended regex {{{(?|.*)}}} does the
 trick).
