Re: [matplotlib-devel] Trying to prepare a pull request but tests.py keeps crashing on master

[Benjamin R. <ben...@ou...>]

When dealing with the C/C++ layer and switching back and forth between
upstream master and your branch, I would suggest running "git clean -fxd"
and then do a complete rebuild. We have recently fixed a number of memory
leaks that may or may not have merged well with your code as it involved
the CXX layer.
