Then maybe we can try catching the culprit. Try this:
(gdb) break buffer.c:1840 if redisplaying_p != 0
This breakpoint is in this snippet from buffer.c:
/* Make this buffer not be current. Exit if it is the sole visible
buffer. */
if (b == current_buffer)
{
tem = Fother_buffer (buffer, Qnil, Qnil); <<<<<<<<<<<<<<<<<<
Fset_buffer (tem);
if (b == current_buffer)
return Qnil;
}
If this breaks, I'd be interested to see the backtrace (including
"xbacktrace" which shows the corresponding Lisp backtrace).
Thanks.
