Comment 6 for bug 1157603

I've cloned the svn repository and this problem persists. This is my clang version:

$ clang++ -v
clang version 3.2 (trunk 159725)
Target: x86_64-unknown-linux-gnu
Thread model: posix

It looks like the ref count of the shared_ptr that holds the internal representation of std::thread gets to 0, so the thread impl is getting destroyed. I can't figure out why this example does actually work on g++ 4.7, since both compilers use the same headers/libs. This could be a bug in libstdc++'s std::thread implementation, if this code didn't work fine on g++.
