hoi list,
i'm experiencing a weird problem, and i hope someone can point me
in a good direction.
i'm working on a slideshow application that uses quartz-
compositions for the transitions.
i a later stage i'll probably wrap those .qtz-files inside plugins/
bundles, but for now i'm dynamically loading the files in a
QCrenderer when they're needed.
this all works perfectly well, except for the fact that the app.
always crashes when it shows the 34th image, and starts loading the
35th photo and the asociated transition-file.
it's always the 34th image/transition that it crashes on,
regardless what images, transitions (playlist) it's rendering. so
for instance a playlist containing only 3 images/transitions which
is looping, will also crash whenever it starts the 35th transition.
i can't see the logic in this number 34. as far as i see it's got
nothing to do with memory problems, since plenty RAM is available,
and the app isn't leaking.
in what direction should i possibly look for an answer?
is there some underlying caching mechanism that gets stressed too
much?
or other things i don't know about?
or is 34 actually the real answer to the question of life, universe
and everything:?
thanks
arri

and the debugger hangs on this line:

..which has by then been called before succesfully 33 times.
renderer is a QCRenderer, which looks fine in the debugger.
