Only thread is [5304] Main Thread at that point.

#62 This is what you get when it deadlocks. Note it was showing 8 threads before so all of those threads are being created then cleaned up.

#63
Am I understanding you correctly that at the time ThreadPool::shutdown() is entered, only the main thread is left? If so, it should not do any Thread::join()s. If it does, it looks like the worker threads have been killed off before without getting a chance to clean up.

You could set a breakpoint in the if-conditional "if( checkForStop() )" in ThreadPool::WorkerThread::run() and see if and where that triggers. This should lead to the semaphore being released.

ATM, I can't think of how the semaphore should lead to a race condition but that's not meaning much. There's been some changes for B4 but nothing crosses my mind that could tie into this (except the aforementioned deadlock with Platform::forceShutdown).

#64 RE //FIXME
Yes, you need to do a build. In your project directory, there's a "generateProjects.bat" file. Run this and then open the solution file in "buildFiles/Visual Studio 2008/" and do a build. This should solve the problem.

I just tried this and no changes. still freezes and no sound.
is there something I am missing in how to recompile.

#65 @Donald
Hmm, if you applied the code change, run the batch file, and then compiled your project, it should work. Are you running the correct executable? The project will come out in debug build by default, so you have to run <projectName>_DEBUG.exe rather than r<yourProjectName>.exe.

B4 is round the corner, though.

#66 how can i fix this problem if I have the binary version of T3d 1.0.1 ?
