 tests are working fine for me, MacOS/ARM

 Hi @pramsey, sorry for the delay - I realized I'm not getting any emails
 from this just now.

 We're working with X86 server running Alpine 3.22 images on production.

 Even on Mac I'm seeing this issue, but I'm not running natively.

 The test case in the original issue still yields 0 as distance.
