You're welcome ;-)

Here is the relevant ./configure stuff. I left out directory options:
--host=powerpc-linux --disable-rpath --disable-nls --with-pic  
--enable-gtk-cairo  --enable-pure-java-math --disable-sound 
--with-system-zlib --with-engine=intrp --with-threads=unix-pthreads  
--cache-file=../powerpc-linux.cache

The cache-file sets:
ac_cv_file__proc_self_maps=yes

In meantime Philipe Laporte sent me a link to a similar classpath bug:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27118

I think it is the same bug, the stack traces look very similar.
The reproducer gives the same results as the Swing demo.

Yes
