Comment (by michaelld):

 @petrrr: I did the same: updated `*gcc12*`, cleaned `py*-numpy`, then
 tried again. Exact same errors as before & what you're seeing. I ''think''
 this is a compiler error, but it might be due to specifying flags that
 result in bad code on the target CPU (e.g., `-msse3` then the CPU doesn't
 support it) -- probably not since I don't think that's how most compilers
 work, but throwing it out here just in case that resonates with someone.
