Using an anonymous global union causes g++ 3.4.2 to segfault on a Sun Ultra 5 running Solaris 8. Giving the anonymous union a name or making it a local anonymous union allows it to compile successfully. A test compile of the same code minus the -mcpu=ultrasparc flag on a SUSE LINUX 8.2 box using g++ 3.3 compiles successfully with no errors using the same anonymous union. I will upload the small test files if I can find the option to do it.
