I think libgcov uses the dynamic linker's malloc (so Emacs has *three* malloc implementations) and our trick for switching from the Emacs malloc in temacs to the system malloc in bootstrap-emacs won't work for memory allocated for --coverage. Unfortunately, the libgcov actions do not seem to be easy to disable in temacs and re-enable in bootstrap-emacs. I suggest that we just say this combination isn't supported; if you want to build Emacs with gcc --coverage you can configure with CANNOT_DUMP=yes. If the portable dumper ever gets working, --coverage should be easy to support, of course.

I hope Paul will look at this, but personally I'm very surprised that "--coverage" at all works in a dumped Emacs, given the way it's triggered (ctors and dtors). It would be nice to have it working, of course, if that's feasible.
