The compiler get's a segmentation fault on this one :)
The compiler 4.0.0 was configurated with  --enable-languages=c,c++,java
--enable-shared --enable-threads=posix --with-cpu=i686 and built with make
CFLAGS='-O' LIBCFLAGS='-g -O2' \
            LIBCXXFLAGS='-g -O2 -fno-implicit-templates' profiledbootstrap
