[Boost-users] BoostTest: Is BOOST_MESSAGE is not thread safe?

23 Mar 2010

      Guys,

I've just noticed BOOST_MESSAGE is not thread safe instruction.
It is unbelievable!! I do not want to believe it!!!

Try this:

#define BOOST_TEST_MAIN
#include <boost/test/unit_test.hpp>
#include <boost/thread/thread.hpp>

void foo()
{
   for( size_t i = 0; i < 100000000; ++i )
   {
      BOOST_MESSAGE( "111111122222222223333333333" );
   }
}

BOOST_AUTO_TEST_CASE( testBoost )
{
   size_t const SIZE = 2;
   boost::thread t[ SIZE ];

   for( size_t i = 0; i < SIZE; ++i )
   {
     t[ i ] = boost::thread( &foo );
   }

   for( size_t i = 0; i < SIZE; ++i )
   {
     t[ i ].join();
   }
}
