[Bug c++/24302] New: anonymous global union segfault with g++ 3.4.2 on solaris 8

[jack dot alderson at xfab dot com]

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.
