There wasn't much feedback overall, so I'll just say that I'm happy you've
put some effort into this. Thanks!

I'm all for uploading wheels for those older versions to reduce build times
for users. Even in the worst case, we can always take them out if anything
goes really wrong.

[Cython] Cython compiler crash in 0.24

[Isuru Fernando]

Hi,

When cythonizing a .pyx I get an error in Cython 0.24 which was not there
in Cython 0.23.3

After printing the stacktrace, this seems to be because of this line
https://github.com/cython/cython/commit/6d55fd189f6ee9d4374d00b8c9c320bd04332bab#diff-28c66ef9e2ff564619ef82aa9d72ee7dR2762

where a None object is passed and the following line calls the None object.

https://github.com/cython/cython/blob/6d55fd189f6ee9d4374d00b8c9c320bd04332bab/Cython/Compiler/ExprNodes.py#L1780

Let me know if you need more information.

Thanks,

Isuru Fernando

No problem, happy to return something for all the good use I get from Cython.

OK - I uploaded 64-bit wheels back to Cython 0.17 - please let me know
of any problems.

I have built 32-bit wheels as well, but haven't uploaded them as yet.
They are in https://nipy.bic.berkeley.edu/manylinux if y'all want to
test.

Cheers,

Matthew
