segfault bug

[Henry Cejtin]

I  ran the code that is segfaulting on a machine here after re-compiling with
-g (note, -g isn't documented in the man page or in the  html)  and  it  dies
with
    gc.c 421: assert(stack->used <= stack->reserved) failed.
In  the  stack in question, the reserved field is 32768 but the used field is
858,927,408.  This is all using the the 2001-10-06 version.

Is there any way to turn on what used to  be  GC_EVERY_CHECK  in  the  native
backend?
