I still don't know what happened, but it also affected some X.org clients (specifically xsm, the underfeatured session manager). There seemed to be problems resolving font resources, resulting in a NULL FontStruct member, but I can no longer reproduce. I am now observing the issues Jerry reported in From: Jerry James <james(a)xemacs.org&gt; Subject: Bit limitations in lisp-union.h Date: Fri, 09 Jun 2006 18:38:24 -0600 Message-ID: <m3lks5dev3.fsf(a)jerrypc.cs.usu.edu&gt; confirmed by configuring --with-compiler=gcc-4.0 (crash goes away) and --with-bignum=none (crash goes away). To repeat Jerry's report <m3bqstq6gt.fsf(a)jerrypc.cs.usu.edu&gt;, this is a GCC bug, and it's fixed in SVN for gcc-4.1. Consider waiting for gcc-4.1.2 if you're going to build --with-union-type *and* --with-bignum. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
