The backtrace indicates there's infinite recursion in gmalloc.c:

> #365 0x08184f6d in __malloc_initialize () at gmalloc.c:615
> #366 0x081856c1 in malloc (size=3072) at gmalloc.c:982

These two lines repeat themselves again and again, with calls to other
functions interspersed in between.

I'm guessing that the infinite recursion causes Emacs to eventually
run out of runtime stack, and then it dies with the above weird
message, which really tells you that the program is in deep trouble.

If you can step through the code in question with GDB and try to
understand why it recurses, it will help.
