Are you using an NSMutableArray to add QCRenderers?
I had quite the same problem when I've upgraded the system to 10.4.7.
I changed the NSMutableArray with a NSArray and now it works.

I have a cocoa app that needs to be able to render compositions at
different user-selectable resolutions.
I noticed that the QCTV sample at
http://developer.apple.com/samplecode/QuartzComposer_WWDC_QCTV
implements this functionality by releasing its QCRenderers,
resizing the view/gl context, and then loading new QCRenderers.
However, whenever I try this (even in QCTV) I get an
EXC_BAD_ACCESS. A backtrace shows
#0 0xfffeff20 in objc_msgSend_rtp ()
#1 0x987e8114 in -[QCPatch(Private) _cleanup] ()
#2 0x987e7fa4 in -[QCPatch(Private) _cleanup] ()
#3 0x987e7eac in -[QCPatch(Runtime) stopRendering] ()
#4 0x9881ec14 in -[QCRenderer dealloc] ()
I'm running 10.4.7, XCode 2.3
Does anybody have any insight into this? Did this perhaps work in
a previous version?
thanks,
