           Version: 3.0
          Platform: PC
        OS/Version: Linux

I am trying to build httpd-2.0.48 using clang 3.0 (revision 151385) and the
gold plugin. While linking some component of httpd, clang crashes and the
linker command fails as below. I included a -v for full invocation. Newest
clang and binutils versions seem to have the same problem. Do you have any idea
what might be the problem?
