As far as I can tell the code in question is only built on AIX and OpenBSD — are you using one of those two platforms? If not, perhaps the caching problem is coming from somewhere else.
That said, it does appear that calls to `os.Chdir` result in a spurious dependency on the PWD variable: https://cs.opensource.google/go/go/+/master:src/os/file.go;l=340-345;drc=d961b12be9001cf8dbf8f52847607dbf84d94f8d On Thursday, November 23, 2023 at 1:50:04 PM UTC-5 Kevin Burke wrote: > We have some tests that are pretty slow.
