Hi all,

I'm having some trouble with the thread library. When I interrupt a
thread it is causing my application to crash.

Here is a simple test file:

#include <boost/thread.hpp>
#include <iostream>
#ifdef _WIN32
#include <windows.h>
#endif

using namespace boost;
using namespace boost::posix_time;
using namespace std;

void threadFunction() {
  try {
    boost::this_thread::sleep(seconds(10));
  } catch (thread_interrupted&) {
    cerr << "interrupted" << endl;
  }
}

int main() {
  thread myThread(threadFunction);
  #ifdef _WIN32
  Sleep(1000);
  #else
  sleep(1);
  #endif
  myThread.interrupt();
  myThread.join();
  return 0;
}

If I compile this on Linux, or on Windows with MSVC it works perfectly
every time, but if I compile with mingw it *usually* crashes after
printing 'interrupted'. If I put a sleep in between the interrupt and
join though it never crashes, so there appears to be a race condition
somewhere..

Compiled with: i386-pc-mingw32-g++ -mthreads thread_test.cpp
- -lboost_thread -o thread_test.exe

$ i386-pc-mingw32-g++ --version
i386-pc-mingw32-g++ (GCC) 4.4.3

Boost version 1.42

Any help would be appreciated.

Chris.
