I recently upgrade from boost 1.42 to 1.43.  All of a sudden, the project I was working on seems to be throwing an exception before main() is called.  I was able to reproduce this error in the example below.  Using 1.42, it executes just fine.  Using 1.43, an exception is thrown before main is reached.

In some of my classes, I have a static mutex variable that I lock before I manipulate other static variables in the class (as seen below).

main.cpp – Start

#include "Test.hpp"

int main()

{

                Test test;

                return 0;

}

main.cpp – End

Test.hpp – Start

#ifndef DEFINE_TEST_HPP

#define                DEFINE_TEST_HPP

#include <boost/thread.hpp>

class Test

{

public:

                Test();

                ~Test();

private:

                typedef                boost::mutex    StaticMutex;

                static StaticMutex            s_Mutex;

                typedef                boost::lock_guard<StaticMutex>             StaticMutexLock;

};

#endif   //            DEFINE_TEST_HPP

Test.hpp – End

Test.cpp – Start

#include "Test.hpp"

Test::StaticMutex            Test::s_Mutex;

Test::Test()

{

                const StaticMutexLock Lock(s_Mutex);

}

Test::~Test()

{

}

Test.cpp – End

The code above, when using boost 1.43, produces the following error in both VC2010 Express and VC2005 Pro.

First-chance exception at 0x7569b727 (KernelBase.dll) in BoostTest.exe: Microsoft C++ exception: boost::exception_detail::clone_impl<boost::exception_detail::bad_alloc_> at memory location 0x0030f6e4..

The call stack (>>> is where the exception is caught).

Did something change between 1.42 and 1.43 that would cause this?
