Thank you for the explanation! Ping on the patch: We will not guard every asm call with emms_c() and Rich will not change his alloc() implementation for us: Can't we just document that it doesn't work and return to bugs that we can fix? Or should we consider to guard the three calls to mallc(), realloc() and free()? This works here as expected with 32bit musl but likely does not fix the underlying issue.
