See the "Incompatible changes" section of http://wiki.cython.org/ReleaseNotes-0.15 . This change was made to be more compatible with Python semantics. Set this variable to None if you want to use it before you assign it to something else. (Looking at the code, it should probably be 0 or something else, and these variables could be typed as size_t.) - Robert _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
