Just ask Google: http://www.zope.org/Members/chrisw/showaq Thanks Jo. It seems though that there was a branch containing further ZClass fixes that was merged into Zope 2.8 final that wasn't in b2 that fixed this problem.

Given this definition, you can check which implementation is wrong and file a bug report. Looking at the relevant *Acquisition.c files, both implementations of aq_inContextOf(2.7.6 & 2.8.0b2) are identical. The implementation of macros used in this method (isWrapper, WRAPPER, and OBJECT) are also identitcal, there being nothing else immediately obvious that looks like it could have been implemented differently there. I would hence suspect the wrapping, and/or behaviour of the object and/or context to be somehow different?
