Maximum recursion depth exceed numpy, chained call

[gmonkman]

Steps to reproduce

Create a test.py as follows:

import numpy
A = numpy.array([[1,2,3],[2,3,4]])
B = numpy.array([[1,2,3],[2,3,4]])
C = numpy.vstack((A,B)).T

Run:
pylint test.py

Current behavior

Halts checking with: "internal error with sending report for module []
maximum recursion depth exceeded

Expected behavior

Does not halt checking

pylint --version output

pylint 2.3.1
astroid 2.2.5
Python 3.5.4 (v3.5.4:3f56838, Aug 8 2017, 02:17:05) [MSC v.1900 64 bit (AMD64)]
numpy 1.16.2

Actually, rather than the chained, it doesnt appear to play nicely with np.hstack and np.vstack - although I haven't pinned down precisely what arguments call it to fail. However, the above example certainly does fail for me.

Thanks for the report @gmonkman I can reproduce it using --extension-pkg-whitelist=numpy

@PCManticore i'm unable to reproduce it, even with --extension-pkg-whitelist=numpy.
What version of numpy did you use?

[PCManticore]

Hey @hippo91 I can reproduce this issue with the following:

pylint 2.4.0-dev0
astroid 2.3.0
Python 3.5.5 (default, Apr  5 2018, 08:18:31)
[GCC 4.2.1 Compatible Apple LLVM 8.1.0 (clang-802.0.42)]
numpy==1.16.3

[hippo91]

OK. I can reproduce it now. Thanks!

[hippo91]

I think the problem is due to the new array_function_dispatch decorator in the numpy 1.16 version.

@gmonkman this issue shoud have disappeared thanks to pylint-dev/astroid#664.
Can you confirm please? So That i could close this issue.

[hippo91]

@gmonkman i close this issue. If the problem has not disappeared with the next version of astroid do not hesitate to open it again. Thanks.
