Package: libopenblas0 Version: 0.3.10+ds-3 Severity: normal Hi,
a sagemath test segfaulted in libopenblas.so.0 / zgemm_oncopy_EMAG8180 when building on arm-ubc-01.debian.org, see https://buildd.debian.org/status/fetch.php?pkg=sagemath&arch=arm64&ver=9.2%7Ebeta12-1&stamp=1599922222&raw=0 openblas was called by numpy and the issue looks similar to #966175 where the segfault occurred in dgemm_oncopy_HASWELL.
