 Hi,
 
 Yes, please send me your testcase. I have a few comments so far.
 
 - Your report is against gcc3.0-c++-3.0.2-1mdk under Mandrake Linux 8.1. This 
 is odd as we never provided any gcc-3.0.2 in any x86 distribution. Mixing 
 Cooker packages and stable packages is generally not a good idea. Or have you 
 upgraded to Cooker or MDK 8.2 since ?
 
 - 3.0.2-1mdk is mainly based on RH-3.0.1 release 4. I would have expected 
 problems with later releases such as 3.0.3-0.1mdk with several other patches 
 coming in. But your original test case does work gcc-3.0.4.
 
 - 3.1-0.2mdk is a prerelease snapshot as of 2002/04/01 plus the following 
 patches from Red Hat: compat with older 2.96-RH and binutils, and backport of 
 the visibility attribute.
 
 Bye,
 Gwenole.
