[bug] crash using M-% in indirect buffer. 27 years

Karl M. Hegbloom

This is Finnish Landrace with 2 of Hrvoje's indirect buffer patches applied. I was using `c-comment-edit', made an indirect buffer of the comment, which contained a scheme define, switched to the new indirect buffer, and threw it into scheme mode with font lock on. I tried to use M-% to change a variable name in the scheme, and XEmacs exited with a stack trace and core dump. I just verified that this is reproducable; it happens right when I push `y' to replace the first blue highlighted match. I'm not running `-vanilla', but don't feel that it would matter in this case. (obviously tell me if I'm wrong.) Fatal error: assertion failed, file insdel.c, line 2241, orig_end >= buf->text->changes->mc_begin && orig_end <= buf->text->changes->mc_new_end Fatal error (6).

Re: [Russ Allbery <rra@stanford.edu>] Re: Status of pcl-cvs development? 27 years

Greg Klanderman

Jari, I too prefer pcl-cvs. I'm currently synching our (XEmacs) version with Greg Woods' pcl-cvs 2.0b2 and adding several features. This will likely take me another couple weeks. Greg Woods has indicated that he will fold my changes back into his sources and then will officially release pcl-cvs 2.0. I'm currently committing to the repository on cvs.xemacs.org so if you want a look you can. Eventually I hope to get it working on NT too, though I do not actually use NT so I'll need some help there. greg >>>>> "Jari" == Jari Aalto+list cvs <jari.aalto(a)poboxes.com> writes: Jari> Jari> [1 <text/plain; US-ASCII (7bit)>] Jari> I'm posting this frm CVS mailing list to XEmacs beta list in case Jari> you guys want to get together and discuss about development Jari> things.

Re: How to get patches expedited 27 years

Karl M. Hegbloom

I imagine it must already be on the TODO list for `pcl-cvs' to make it so you can tell it where to root patches from? Or does it do that already and I've just not discovered it? Will try and spend a little time looking at that. :-)

You might try poking around on http://cvs.xemacs.org/ and see if you can discover that.

efs bug: invalid function (macro ... ad-get-advice-info 27 years

Karl M. Hegbloom

I tried to use `C' in dired to copy a file over an efs link. It worked the other day before I ran a cvs update of my packages tree, so perhaps a recent change has brought this? I will try and debug it some, but in the meantime, here's a stacktrace for the experts. Let me know if you have already solved this one, please.
