            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 am not sure what to do next.  I tried this:

(gdb) c
Continuing.

Breakpoint 6, Fre_search_forward (regexp=137779403, bound=137779403,

And

I also tried printing the value of `regexp=137779403' and got

(gdb) p
$3 = 137779403

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