 editors/emacs (emacs23) is also crashing, as are some of the other
 emacs versions. See
 http://ftp.netbsd.org/pub/pkgsrc/misc/joerg/20110921.2152/meta/report.html,
 scroll down.

 Might or might not be a single shared issue.

 Just for the record -- I haven't had emacs crashing yet on my
 5.99.55/amd64, gcc-4.5. Neither during build nor later.

 Hello,

 I confirm that emacs22, emacs23 and emacs24 (emacs-snapshot) are 
 crashing while building (at the bootstrap phase) on this night's 
 pkgsrc-current on NetBSD-current/amd64.

 They all work for me. However, it's clear at this point that this
 problem exists and affects some people but not others. Not so clear
 why.

Are you still seeing this problem with the latest emacs-snapshot?
(Or with any other emacs version; if so please be specific)

 This is the same problem with gcc 4.5 that I patched in emacs20 a few
 days ago. So I guess this is a confirmation that emacs22 (and
 therefore, emacs21) needs that fix.

 However, this cannot be the submitter's problem as the submitter was
 using 5.1. Neither can the submitter be having the unwind problem
 tracked in PR 45716, as that also affected only -current.

 I believe at least one other temacs crash in (only) emacs-snapshot got
 fixed upstream.

 Is there a fourth version of this problem?

At this point the only emacs versions still dumping core are xemacs-current
(which has been broken for a long, long time) and mule. At least in any
of the bulk build results I've seen lately. So let's call this fixed.
