 I'm very glad to hear the bug is not present in the systems you tested.
 I'd like to install the released version of gcc 3.3, but as this is a 
 production system I'm working on, I prefer to install rpms from SuSE.
 I do have an old laptop at home, but it's not capable of compiling gcc in a 
 finite time.
 
 If there are any (SuSE or other reliable) rpms with gcc 3.3 I'm willing to 
 test.
