Thanks for the quick reply.
I see two problems:
- re_match_2_internal does get into a seemingly infinite loop
(minutes of CPU time in that function -- though I suppose it
could merely be taking a very long time due to a pathological
re/pattern pair)
- going back into the same loop after C-g seems wrong
I'll try to narrow it down, but will be traveling for a couple
of days, so I probably won't get to it until next week.
