Patch for double free and iteration bug

I'm seeing a struct-reorg.exp ICE on MIPS too, although in
wo_prof_malloc_size_var.i instead of wo_prof_two_strs.c.
ISTR seeing the same ICE you did, but now I just get a
segmentation fault.

As far as the segfault goes, the problem is that we free
a htab from inside a htab_traverse of it.  I also noticed
that a couple of "remove this structure?" loops were skipping
the structure that replaces a removed one.

Could you try this patch and see if it is the same problem,
or whether it's something different?

Thanks,
Richard
