Thanks for the report, I pushed a fix: https://github.com/cython/cython/commit/e9f9fde70d5d96f418244a0640a63a966a2457c1 . Seems like I forgot an error test for that. _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
