721	PGE::P5Regex consumes all memory	coke	pmichaud	"Given this code:
{{{
$ cat regex.pir
.sub ''
   say ""1..2""
   load_bytecode 'PGE.pbc'
   .local string exp, a_string, original_string
   exp      = '($|^X)*'
   a_string = ''

   .local pmc tclARE, rule, match

   tclARE = compreg 'PGE::P5Regex'
   rule = tclARE(exp)
   say ""ok 1""
   match = rule(a_string)
   say ""ok 2""
.end
}}}

running it (eventually) dies with:
