You could e.g. launch some Ubuntu/Debian container (min Ubuntu 20.04 for glibc) and try to run the official v1.35 in there. If there's no startup error, druntime v2.105 probably works. FWIW, the problematic module is https://github.com/dlang/dmd/blob/master/druntime/src/core/cpuid.d. As the name suggests, it uses/depends on the CPUID instruction. I can only tell you that everything works on my workstation, a Threadripper 3960X. --
