Sounds like the memory-related problems are not over yet.
Did you try to invoke temacs, and work in that? IOW, try this:
./src/temacs -Q
It will load a bunch pf Lisp files, and should then present a normal
frame, where you should be able to work as usual. If that does work
on Hurd, I'm pretty sure the problem is with unexec and dumping Emacs.
