 nsm-check-local-subnet-ipv4 test fails on macOS with VPN enabled
Date: Mon, 16 Dec 2024 02:03:53 +0000

I see the below test failure when running with a VPN enabled on macOS.
It fails predictably every time, but when I disable the VPN, the test
passes.

Looking into it, it seems like it's this call that leads to the
backtrace:

    (nsm-should-check "localhost")

However, when edebugging `nsm-should-check` and step through the code, I
do not get a backtrace, and it correctly returns t.

Any ideas for how to continue debugging this?
