This has resolved itself after a couple of Debian updates.  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

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 at jerrypc.cs.usu.edu>, 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.
