            Bug ID: 61639
           Summary: GCC 4.7.4 can't longer compile clang
           Product: gcc
           Version: 4.7.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: alp at rsu dot ru

After updating GCC from 4.7.3 to 4.7.4 I can't longer compile Clang 3.3 (or
3.4.1) on OpenIndiana (illumos distribution).

While linking clang-check I receive the following error:

llvm[5]: Compiling CIndexCodeCompletion.cpp for Release+Asserts build (PIC)
llvm[5]: Linking Release+Asserts executable clang-check (without symbols)

Everything works with GCC 4.7.3

LLVM developers confirmed the issue exists on OSX whith gcc 4.7.4 (but not
4.8/4.9).

4.7.x is not supported anymore, so even if this was a bug in 4.7.4, it is not
going to be fixed.

This bug needs to be redefined as it also occurs with gcc-4.9.1 as well, but
may not actually be a fault of gcc (on a Debian squeeze system with compiled
gcc-4.9.1).

Without a testcase there's nothing to do.
