Another one of these just happened after I had used CVS menus and
played one game of tetris. This time the story ends right in Fcons.
The comments in throw_or_bomb_out() in src/eval.c are scarey enough to
give some clue to the knowledgable. All I can make of it is this:
There is a warning about infinite recursion, which is what seems to be
happening here:
'top-level. If this tag doesn't exist (happens during the
initialization stages) we would get in an infinite recursive
Fsignal/Fthrow loop, so instead we bomb out to the
really-early-error-handler.
There problem is: We don't bomb out in throw_or_bomb_out():
if (!bomb_out_p)
tag = Fsignal (Qno_catch, list2 (tag, val));
else
call1 (Qreally_early_error_handler, Fcons (sig, data));
