Recently I've been looking at errors in the matplotlib test suite when building on Fedora's ppc64 arch, which is big-endian. I've sent a few PRs so far, but there are still some remaining issues, so I'm filing tickets for them.
This ticket is for a failure of the test_png.test_pngsuite.test test. In my ppc64 build, this is the image produced by the test:
Here's the expected image:
The fifth, seventh, thirteenth and fifteenth images clearly differ. Haven't yet dug into why this is.
There is another png-related test that fails, the two may share a common cause:
