--- Comment #24 from Alexandre Julliard julliard@winehq.org 2008-02-26 03:36:18 --- The bug is that the app is accessing the internals of the activation context, and passing the magic number as a pointer. It looks like it's confusing an activation context stack frame with the actual context. Of course never returning a context at all from QueryActCtx would fix it, but I have a hard time believing that it's the correct fix.
