Comment (by Peter.Danecek@…):

 I experience crashes of xemacs which might be related, at least to me very
 similar. I realized it occurs when I activate "syntax highlighting", which
 was activated automatically first.

 My OS version is Mac OS X 10.5.8 (9L31a
 Xcode 3.1.4
 Component versions: DevToolsCore-1204.0; DevToolsSupport-1186.0
 BuildVersion: 9M2809
 MacPorts base version 2.1.2 installed

 For me the problem appeared only with the update to xemacs @21.4.22_5, so
 I switched back to xemacs @21.4.22_4, which for me works fine. However,
 now xemacs @21.4.22_6 links against libpng @1.5.12_0 and it becomes less
 practical to stay with the older version. As this problem appeared only
 with a port revision I would assume it is NOT a problem of the xemacs
 release itself.
