LLDB compile problem: contradicting exception specifications

Dear All,

I am trying to build LLDB on Mac OSX Snow Leopard using command line
build as per instructions from the web page http://lldb.llvm.org/build.html

Since XCode does not worked for me, I am trying the autotools & make
based build.

After checking out llvm and then clang and lldb into the tools
directory of the llvm tree, I configured with:

> myllvm : root of llvm tree
> myllldb : tools/lldb in llvm tree
> mybuild : build directory outside the trees

> cd ${mybuild}
> ${myllvm}/configure --enable-cxx11 --enable-optimized
CC=/opt/local/bin/gcc CXX=/opt/local/bin/g++

and build with

> make DEBUG_SYMBOLS=0 CC=/opt/local/bin/gcc CXX=/opt/local/bin/g++

The used compiler is MacPorts' gcc-4.7 / g++-4.7

LLVM compiles fine, Clang required me manually create
"${mybuild}/include/clang/Config" and then symlink the
"${mybuild}/include/llvm/Config/config.h into it.

Clang compiled fine afterwards.

Compiling LLDB now fails with:

The checkout is from Jan 28th, revision 200341.

How can I fix the problem, i.e. which exception specification is the
right one?

Best regards
