I'm having trouble reproducing this on any of my setups though.

Re: [Cython] Cython 0.25 released
I plan on releasing https://github.com/cython/cython/archive/0.25.1b1.tar.gz later today. I'd like to figure out the CentOS issue, but can't reproduce. (To reiterate, if you were broken by this release, this is what prereleases are for :). Bugs fixed -- * Fixes a bug with ``isinstance(o, Exception)`` (Github issue #1496). * Fixes bug with ``cython.view.array`` missing utility code in some cases (Github issue #1502). Other changes - * The distutils extension ``Cython.Distutils.build_ext`` has been reverted, temporarily, to be ``old_build_ext`` to give projects time to migrate. The new build_ext is available as ``new_build_ext``. On Wed, Oct 26, 2016 at 9:15 AM, Robert Bradshaw wrote: > I'm having trouble reproducing this on any of my setups though.
