================================================================
Dear Bug Team!
I can repeatably hit the following ABORT() in window_loop():
/* #### Still needed ?? */
/* Given the outstanding quality of the rest of this code,
I feel no shame about putting this piece of shit in. */
if (++lose_lose >= 500)
{
/* Call to ABORT() added by Darryl Okahata (16 Nov. 2001),
at Ben's request, to catch any remaining bugs.
If you find that XEmacs is ABORTing here, and you
need to be up and running ASAP, it should be safe to
comment out the following ABORT(), as long as you
leave the "break;" alone. */
ABORT();
break; /* <--- KEEP THIS HERE! Do not delete! */
}
The following steps cause the abort to occur:
1. Start XEmacs under X
2. M-x make-frame-on-display RET remotehost:0 RET
3. Minimise the original frame with C-z
4. On the remote system, M-x shell
The problem doesn't occur if step 3 is omitted.
However, I can't reproduce this with -vanilla. This appears to be
connected with the fact that my init files set shell-multiple-shells
to t and create two shells (so step 4 creates a third). If I kill
those first, the problem disappears.
BTW, the src/.gdbinit file doesn't work for me; it complains with:
> pobj which_frames
No symbol "Lisp_Type_Char" in current context.
Let me know if there are any other tests which might be useful.
