Same problem with

clang version 3.2 (branches/release_32 170508)
Target: x86_64-unknown-linux-gnu
Thread model: posix
OS: Fedora 17
gcc version: 4.7.2 20120921 (Red Hat 4.7.2-2)

the backtrace:

66 {
67 thread::_Impl_base* __t = static_cast<thread::_Impl_base*>(__p);
68 thread::__shared_base_type __local;
69 __local.swap(__t->_M_this_ptr);

it seems that __t->_M_run is a pure virtual function, so the process have been terminated.
