Gcc 3.3.2 failed to compile a working glibc due to a missing patch: http://gcc.gnu.org/ml/gcc-patches/2003-04/msg00392.html As the result, glibc doesn't work correctly on ia64: http://sources.redhat.com/ml/libc-hacker/2003-10/msg00011.html
Created attachment 4945 [details] A patch
Jakub added the patch to the gcc-3.3 branch 2 days ago. There is expected to be another gcc-3.3.x release, so this will be in gcc-3.3.3.
