string tests sometimes failing on macOS (Github Actions) #8353
Description
This one's a bit of a headscratcher I've seen twice now:
Testing low-level functionality
Testing builtin_string
Error: Test failed on line 5674: [string match -r \(\?=ab\\K\) ab]: expected return code 0 but got 2
Error: Test failed on line 5674: [string match -r \(\?=ab\\K\)..\(\?=cd\\K\) abcd]: expected return code 0 but got 2
Encountered 2 errors in low-level tests
Rerunning seems to fix it, but I have no idea why? What even could be racing here?
I don't know if https://github.com/fish-shell/fish-shell/runs/3895703216 is a stable link (I sure hope it is).
