llvm dev - Jul 2007 - [LLVMdev] Problem compiling llvm-gcc

I compiled LLVM with this script:

-----------------------------
#!/bin/sh
PATH=/usr/lib/cache:$PATH

cd llvm
test -f Makefile.config ||
        ../llvm/configure \
        --prefix=/usr/src/llvm/dist \
        --enable-optimized \

make
make install
----------------------------



The I've got llvm-gcc 4.01 via subversion URL 
svn://anonsvn.opensource.apple.com/svn/llvm and tried to compile this 
as well:

----------------------------
#!/bin/sh
PATH=/usr/lib/ccache:$PATH

mkdir -p obj-gcc

cd obj-gcc
test -f Makefile ||
        ../llvm-gcc/configure \
        --prefix=/usr/src/llvm/dist \
        --enable-llvm=/usr/src/llvm/llvm \
        --enable-languages=c,c++

make
----------------------------



However, I've got an segmentation fault while it tried to istream.o:

----------------------------

Now, xgcc is from llvm-gcc, so I'm not sure if my locally installed GCC 
compiler is at fault, which is "gcc (GCC) 4.1.3 20070629 (prerelease) 
(Debian 4.1.2-13)"

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
----------------------------

This did produce the same error.

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,

Marco

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!

Thank you, this also fixed my problem.
