Unfortunately due to a bug in gcc 4.5, Dag and I have concluded that we must disable nested parallelism support in Cython, as there is no suitable workaround. (The issue is that the bug doesn't propagate lastprivates, which results in random values for inner privates.) The reduction fails in the test due to yet another bug, which can be worked around easily. So Robert, please wait with the next release candidate until I have disabled nesting and the corresponding tests and documentation. _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
