Please tell us exactly what value is used for GC_MARK_STACK; as Eli said:

   It's a macro set in src/lisp.h.  You can check it with #warning or
   some such

This said, since you have mark_memory in your backtrace, that indicates
that GC_MARK_STACK is probably set to GC_MAKE_GCPROS_NOOPS, as usual.

Maybe complete backtrace would help, tho.
Also, it'd be useful to know what were the last few keys (the "lossage").
