Likewise, gcc 3.0.2 is not ABI compatible with 3.0.1. IA-64 gcc development was not finished before the gcc3 release process started, so our choice was to tell everybody not to use GCC3, or to try to finish it during the gcc3 release process and warn people about ABI compatibilities. We choose the latter approach. I don't have a copy of the SuSE OS release, but it sounds like it was built using gcc-3.0. Thus gcc-3.0.1 is not supported on this system. It will work most of the time, but it will fail in some cases when trying to link gcc-3.0 compiled shared libraries into gcc-3.0.1 compiled applications. That is exactly the problem you ran into. The only good solution is to recompile all system libraries (e.g. glibc) with gcc-3.0.1, but that will be difficult and time consuming. It is probably better to not use 3.0.1, or wait for a new OS release built using a later compiler. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&pr=3796&database=gcc
