Hi,

While attempting to update numpy to 1.21.3, I encountered the following
failure only on an older Q6700 (Core2Duo) Intel processor:

I'm not sure what's at cause; I have the same problem when testing
against the current 1.17.3.

Thanks,

Just a shot in the dark, but could this be related to the compiler version 
in the master branch? Does the problem still happen on core-updates-frozen?

The problem occurred on the cufbc branch; I guess it'd happen the same
on cuf, but I haven't checked.

I should try it on master!

Hi,

This is fixed on core-updates-frozen with commit 9e497f44ba.

Thanks to Efraim for suggesting it.

Closing.
