re_match_2_internal
... is the inner function that does regexp matching. Could you
please show a backtrace of the inner 5 or 10 C stack frames that call
it? Then we will see which C primitive was called.
Also, by looking at the args to that C primitive, you can see
what the regexp is.
Is this what you mean?

I do not know what to try next. What should I do?
