[perl #123840] hang in re_intuit_start
Message ID:
I tried looking at the second case a bit, '"\x{100}bcd" =~ m{\C\x{80}a?bc}'. I feel one of the underlying problems is that CANY claims to be SIMPLE, implying that it consumes exactly one character; I had a stab at making it VARYING (min 0, delta 1) instead, but haven't worked out the precise incantation to avoid breaking everything.

I wonder if \C has been deprecated long enough we could consider removing it: it violates a bunch of stuff we really want to assume.
