Extended Description

Using svn-bisect, I have determined that revision 131365 introduced an assertion which is failing on one of my Objective-C++ source files. (The failure occurs at both that revision and through to the current trunk.) Clang was built as Release+Asserts

You can view the file in question here: http://cvs.tekkotsu.org/viewvc/Tekkotsu/local/DataSources/CameraSourceQTKit.mm?view=markup

I will append the assertion failure report from clang below, let me know if there is anything else I can provide to help resolve this, thanks!

I just tried again with rev 142047 and things look happy now, so I guess this got fixed, thanks :)
