Can you give an exact recipe starting from "xemacs
-vanilla"?
Yes. It took quite some time, but I can now. It seems that completion
is also involved (I have some kind of deja vu -- didn't I report
nearly exactly the same problem some time/beta version ago?). Anyway.
Here you go:
1) Fire up xemacs -vanilla
2) load-library completion
3) M-: (initialize-completions)
4) load-library cperl-mode
5) load-library font-lock-mode
6) Load the following file (without the lines, of course):
--8<------------------------schnipp------------------------->8---
#!/usr/bin/perl -w
# $Id: $
my $test_program;
--8<------------------------schnapp------------------------->8---
7) Ensure you have cperl-mode and font-lock enabled in that buffer.
8) Move to (beginning-of-buffer)
9) Hit the key 'm'
10) See the backtrace in your gdb.
Without completion, I can't trigger the bug. I moved my
.completions-file out of the way, to no avail. completion is from
xemacs-packages. I have no idea what version, put the changelog in
completion.el talks about some version 10. BTW: This recipe also works
in an older XEmacs 21.5b-18, hence it's probably not a new problem.
Hope that helps,
Holger
