It does look pretty suspect. There is loads of 'passing the pointer
being done'. How rare are systems without REGEX_MAY_ALLOC? I suspect
this case is exercised less. However it migth well be that the
particular rexexp ist just never GCed.
Well, if it is a real memory leak, it's not being caused by GC.
This particular memory block is part of a non-lisp global variable.
However, I can't find any place where this leak could be caused. I'm
wondering if temacs is zero'ing some global memory before it exit()'s
(in which case this would not be a real leak).
If I have time (which I probably don't), I'll try to step through
temacs to see where the leak is occurring.
