one thread hanging in RWTPtrSlist<POSIXThread>::append

[oshinonline]

Hi,

In my application I have RWTPtrSlist<POSIXThread>, where POSIXThread is
my wrapper class. Whenever I create a new thread I call append on the
list. But it hangs after I created 11/12 threads.
Here is stack Trace:
Thread 5 (system thread 3513041):

You'll do better on a group dedicated to your platform.

could u suggest me some hint, where can the problem be?

Well three hints, I'm not called u, read up on correct quoting
(<http://cfaj.freeshell.org/google/>) and search for a more appropriate
group, you problem appears very platform or tool specific.

Also post some code.

If your list is not protected by a mutex, you are going to run into trouble.
Make sure only one thread at a time can append to the list.
