Re: [xine-devel] 0.9.9-CVS progress test report

Hi,

I have been digging deeper into my img assertion
problem, and I was wondering how many threads are
manipulating the link list at any one time? My box is
an SMP box, and so two threads are allowed to run
simultaneously. Therefore suppose that two threads
each have a reference to the same image object, and
then one puts this image onto the linked list. If the
second thread now tries to put the same image onto the
list then the assertion will fail. Note that the
queue's mutex would not help us here.

What I am seeing at the moment is the
picture->backward_reference_frame->next pointer
becoming != NULL.
