Hi Maintainer Numpy 1.18.0 unconditionally adds -std=c99 to C compiler options. This causes a change in floating point precision at least on s390x and i386. This was noticed in Ubuntu's autopkgtests for python-meshio [1], see, for example, the failed log of the first test against numpy/1:1.18.3-1 on 2020-05-01 02:07:52 UTC. I've confirmed this behaviour on zelenka.debian.org with numpy 1:1.19.4-1. This was fixed upstream on 2020-08-27 [2]. I'll attach a patch to this bug shortly. Regards Graham [1] https://autopkgtest.ubuntu.com/packages/p/python-meshio/groovy/s390x [2] https://github.com/numpy/numpy/commit/a7401aee4d6d465977760e9e4b16f793d60f4ee4
