            Bug ID: 23429
           Summary: IBM Power8 (ppc64le): libstdc++ std::thread, when
                    compiled with clang, "pure virtual method called"
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++11
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

cat stdthreadbug.cpp
#include <thread>

int main()
{
   std::thread t([](){});
   t.join();
}

$clang++ -v
clang version 3.7.0 (trunk 236572)
Target: powerpc64le-unknown-linux-gnu
Thread model: posix

$clang++ -std=c++11 -pthread stdthreadbug.cpp -o stdthreadbug 

$./stdthreadbug 
pure virtual method called
terminate called without an active exception
Aborted

Note that this works:

cat stdthreadbugkludge.cpp
#define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_1
#define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_2
#define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_4
#define __GCC_HAVE_SYNC_COMPARE_AND_SWAP_8

#include <thread>

int main()
{
   std::thread t([](){});
   t.join();
}
