I think the next step is to add the missing freeze_pattern calls and

I think the missing freezes are 100% a bug, and they should be fixed.

Do you want to do that or should I?

(BTW, I just now noticed the "->buf" at the end of the "bufp = &compile_pattern (regexp,...)" that I complained about. That explains it. Nice :-/.)

Another side question, if I may: Have you perhaps heard of someone producing a static call graph for Emacs, or better yet, specific functions in Emacs? Maybe using objdump -D or something similar?
