I'm running builds on an Arch Linux based docker container with Clang and LLVM tools with version 13.0.0 (rel version 2, for clang, on Arch Linux) on this target CPU https://termbin.com/82n2 . I'm also using ccache 4.4.2 to speed up builds.
I've done a full clean build and logged it here https://ipfs.io/ipfs/bafybeia4kdu4a55fcp5nfntwcqe33aucuwv3uacelmo6zcsmasnsuafvim/ . I'm sorry for including that many flags, but I have an automated CMake bootstrap script to do it but some of them are the default values.

I tried to debug this a bit and figure out if there is a combination of flags that can succeed. I consulted the infrastructure repository and confirmed that sanitisers are being built with gold linker. So perhaps is this something linker related? I can try gold if it is worth trying.
