This report is incomplete
When building with GCC 4.2 from the 4.2 branch, all the demos in demos/jfc and
the gcjwebplugin crash. Lowering the optimization for the jdk to -O2 results in
working demos and plugin. The build with GCC 4.1 does fail for me on amd64, GCC
4.3 from trunk works fine with -O2 and -O3.
