While recording using QTCaptureMovieFileOutput, QTKit calls +[NSBundle
bundleForClass:] on a background thread.
RubyCocoa patches +[NSBundle bundleForClass:] in mdl_bundle_support.m.
For reasons I have yet to figure out, when called on a background
thread, this eventually causes your app to die a horrible death with
"stack level too deep (SystemStackError)", and a badly smashed stack.
Maybe it's just a ruby threading problem - I can't see any way that
RubyCocoa would descend into calling ruby code from within the
rubycocoa_bundleForClass method.
A sample project demonstrating this can be found here -
http://steelskies.com/QTKitTests.zip - it simply kicks off a
background thread, then repeatedly calls bundleForClass:. If your
experience is anything like mine, it ought to crash after around 10
seconds.
If anyone has a workaround (short of just compiling my own RubyCocoa
that doesn't patch bundleForClass:), I'd love to hear it.
