A normal leak would not likely bring a byte compile session to a
standstill.  It is more likely that you have run out of pure space when
dumping Emacs.  When that happens, garbage collection is no longer done
at all.  If you write
M-: (garbage-collect) RET
and get nil, this has happened.

Try recompiling Emacs and watch for "pure space overflow".
