Yes, that makes sense. More generally, the CANNOT_DUMP code has been suffering from bitrot for some time. I just now made a pass through it to fix some gotchas and installed the attached into Emacs master. It's still a mess, but at least I can now do 'configure CANNOT_DUMP=yes emacs_cv_var_doug_lea_malloc=no' and run 'make check', and most tests pass. Hope this helps.

Can we hope that you're working on supporting a fast CANNOT_DUMP implementation? That'd be nice....
