[Sorry if I forgot some of the context here.]
If you don't get the same result when not running under dbx, and you
want to debug this, options are:

1) Use gdb.
2) Try "ignore SIGSEGV" in dbx.
3) Debug a core dump instead.
4) Explicitly set GC_stackbottom (e.g. to the address of a global in
main, if all heap manipulation is done in functions called by main)
before entering the collector the first time, so that the collector
doesn't go looking for it.
