Closed issue by ahesford on void-packages repository https://github.com/void-linux/void-packages/issues/34673 Description: This issue tracks the issue described in 722054111e50649f3381906c9a646f44adb5cc02: >Python code built around python3-numpy and python3-scipy (both linked with openblas) began emitting warnings after the 0.3.19 update: >```python > /usr/lib/python3.10/concurrent/futures/thread.py:58: > RuntimeWarning: overflow encountered in multiply > result = self.fn(*self.args, **self.kwargs) >``` > >that broke program behavior in an Azure VM environment using Intel Xeon Platinum 8272CL CPUs; the problem was not seen on an AMD Ryzen 5 3600 or an Intel Core i7-9750H. Downgrading openblas while leaving the rest of the stack untouched eliminates the problem. > >Unfortunately, I do not yet have a proof of concept that can be shared publicly or more detail about the specific failure, but let's revert to the last known good version until a specific cause can be identified.
