I know that this is not the intended usage of the pthread library (as it
uses pthread for the main thread),
but the following program leaks two blocks of memory (with
pthreads-snap-2002-03-02):

#include <crtdbg.h>
#include <pthread.h>

int main()
{
// turn on leak detection
  int dbgFlag = _CrtSetDbgFlag(_CRTDBG_REPORT_FLAG);
  dbgFlag |= _CRTDBG_LEAK_CHECK_DF;
  _CrtSetDbgFlag(dbgFlag);

  pthread_setcancelstate(PTHREAD_CANCEL_DISABLE, NULL);
  return 0;
}

Supposedly, the setcancelstate creates a mutex that is never freed (the
equivalent mutex is freed though
when a posix thread exits).
