No bells, but this is hipe_find_sdesc() getting a NULL dereference
while trying to look up the "stack descriptor" associated with a
native return address just loaded from the native stack. Obviously
that error is not supposed to happen.

It could be a logic error or a memory corruption elsewhere that's
tripping us up here.

A test case would help greatly.
