numpy crashes on latest linux buildbot
Closed, ResolvedPublic


System Information

Blender Version
Broken: 5552e83b53
Worked: 2.78a

Short description of error
numpy arrays make blende crash

Exact steps for others to reproduce the error
execute this 3 lines in the python console of Blender's UI

import numpy
a = numpy.array([[3, 2, 0],[3, 1, 0]], dtype=numpy.int32)

blender crashes.
Crash isn't present on Win7 and MacOS and disappear on Linux if numpy is bumped to 1.12



Event Timeline

I can confirm the crash on Ubuntu (see attached system-info.txt and blender.crash.txt)

(this is with the official 2.78b linux download from the site)

Bastien Montagne (mont29) triaged this task as Normal priority.

@Sergey Sharybin (sergey) so, looks like you’ll have to update your release build environment? ;)

For the records, official numpy version is currently 1.10.1 (afaik, that’s what defined in anyway).

confirm same issue in 2.78b (numpy 1.10.1 as per latest download from blender site) but not previous versions.
I get same crash executing john peterson sample in python terminal, however if I paste into Text editor it runs ok. However if I alter it to

import numpy
a = numpy.array([[3, 2, 0],[3, 1, 0]], dtype=numpy.int32)
a[:,0] *= 1

it crashes with the following (don't know if this is relevant or helpful info)

Seems something went wrong with compilation of numpy. Did a fresh git clone of numpy, checked out to v1.10.1 branch (currently official version we bundle) and the issue is now gone.

Oh well, give it a test with latest builds from buildbot and the issue should be gone. Hopefully! :) Let me know.

P.S. Seems managed to address such an annoying issue just before 2.78c. Redoing Linux builds now.

Confirm that the issue seems to have gone with latest build on my machine. Thanks

yep, latest buildbot works. Can be closed.
