The advent of the zig build system on edge introduced a bug on
macos-aarch64and possiblylinux-aarch64as well. This bug presented as random loom corruption after heavy workloads such as booting from a pill or recompiling arvo several times. The root cause ended up being buggy assembly in GMP 6.2.1. We had disabled assembly altogether formacos-aarch64in Bazel:vere/bazel/third_party/gmp/gmp.BUILD
Lines 22 to 23 in be3b042
The buggy assembly can be reproduced in isolation by downloading GMP 6.2.1 on a
macos-aarch64machine, running./configure --disable-share --with-pic, and then runningmake checkand looking at all the failing tests. This issue has been fixed in 6.3.0 and the random loom corruption does not happen with these changes.cc @ripperi
