I'm now trying to compile llvm-gcc with

----------------------------
make CC=gcc-4.2 CC_FOR_BUILD=gcc-4.2 CXX=g++-4.2 CXX_FOR_BUILD=g++-4.2

What if you configure llvm-gcc with --disable-shared?

I encountered the same error and the nice people from the llvm irc-channel suggested the attached patch. It enables compiling llvm-gcc for me, but i have not yet done any further testing and i also have no idea if this is the right way to fix the problem.

Hope that helps,

Nice. I will give it a try. I was trying to reduce a test case, but it
is a bit hard. I have a cpp that crashes cc1plus, but the resulting
.ll works opt!

Hope that helps,

I mean that
opt -std-compile-opts test.ll
works...

A somewhat reduced test is attached in case someone wants to reduce it further.
