Same here. However, I seem to recall some similar types of crashes
reported, on an Apple list, that were as a result of changes in the
libraries, changes that meant 64-bit libraries were being used where
defines were designed for 32-bit uses. In the Apple crash report it
looked as though the crashed thread was 64 bit. But the compilation and
system type looks like it is assumed to be a 32-bit.
On my SL system, I saw problems before I added "-arch i386" to my
compilations when I was using parts of Macports or other self-compiled
libraries (as I do in XEmacs). If you try that, does it fix the problem?
Note, I am an English teacher, not a programmer, so take what I say
about causes the way you might other cargo-cult suggestions.

Not really much the Crash Reporter hadn't shown...
