[cfe-dev] clang libc++ libcxxabi std::thread std::async

[David Irvine]

I am curious if anyone has been able to get clang++ to run std::async in
linux at all. If so the process would be great. I have tried TOT + libc++,
with stdc++ and also the recently released binaries. In no configuration
can I get this to work. As recently reported (not by me) in another mail
(lost now), the following fails :

#include <thread>

   void f(){}

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

compiled with

clang++ -std=c++11 thread.cc -o thread -pthread

output

 ./thread
pure virtual method called
terminate called without an active exception
Aborted (core dumped)

using

clang++ --version
clang version 3.1 (tags/RELEASE_31/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix

std::async seems to fail at runtime, I think this is due to abi issues but
cannot be sure.
