Extended Description

clang -v
Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin11.2.0
Thread model: posix

When compiling the attached test.cpp with:

clang++ -I/opt/local/include test.cpp

clang++ consumes multiple gigabytes of memory. Note that um_nodes(g) is a mispelled variant of num_nodes(g) of boost. The opt/local/include directory contains a boost 1.48 installation (macports)

[efriedma-quic]

Please attach preprocessed source (from "clang++ -E").

[llvmbot]

clang++ -E -I/opt/local/include test.cpp > clang.e.out

I can reproduce with Apple clang-211, but this appears to be already fixed on trunk.
