I have modified osgunittests so it now has a function that tests the creation, start and deletion of a thread, as per code example, you can run it via: osgunittests thread With the yesterdays code it worked fine on my system about 2/3rd of the times that it was run, more if I didn't add the delay (this is now a Thread::microSleep). The tests I did yesterday were done without the delay which is probably why I didn't see any crashes after my first round of fixes yesterday. Armed with a relatively reliable means for recreating the crash I've now set about refactoring the OpenThreads::Thread code so that instead of using a mutex in the start method and destructor it uses a OpenThreads::Block in the Thread::start() method and static StartThread() function such that the thread that calls the thread->startThread() will be held back until the new thread has been successfully started. With this change I'm now able to run the osgunittest thread test 1000 times without error (I use a repeat script to do this). I have also rolled these changes into Windows and IRIX spoc code paths, revert the previous Mutex based code. Could you check out the latest version in SVN and let me know if this problem is now properly fixed.
