The flakiness in build results we are seeing on mips* due to that can be a problem in general. You just got first-hand experience on the impossibility of debugging a problem that happens only on some buildds. ARM builds are currently a variety of hardware, and there are literally dozens of cpu feature extensions some whom are implemented on a given cpu. On x86 it is out of your control whether all buildds are Intel or all buildds are AMD or whether buildds are mixed. > Drew cu Adrian BTW: xtensor-blas/mipsel did just FTBFS due to this problem: https://buildd.debian.org/status/fetch.php?pkg=xtensor-blas&arch=mipsel&ver=0.19.1-6&stamp=1635332411&raw=0
