#!watchflakes
post <- goos == "openbsd" && (`runtime.throw` || `Test ".*" ran over .* limit` || `panic: test timed out` || `fatal error: all goroutines are asleep`) && !(log ~ `unexpected fault address 0x349dc4`) && date < "2023-08-01"

OpenBSD has been seeing a steady stream of what looks like memory corruption resulting in runtime throws.

Sorry, but there were parse errors in the watchflakes script. The script I found was:

#!watchflakes
post <- goos == "openbsd" && `runtime.throw` || `Test ".*" ran over .* limit` ||

And the problems were:

script:3.1: unexpected end of script

Because #34988 is still open these memory corruption issues are difficult to detangle from these being real runtime issues (vs. fork corruption).

@golang/openbsd Can you please take a look at these and let us know what you think?

I'll do some poking - Is the process of adding build servers documented anywhere? 6.8 and 7.0 are both pretty old at this point (7.2 and 7.1 are the official OpenBSD supported releases atm), might not be worth tracking down issues on older releases that won't see fixes anyway (if it's an OpenBSD problem)

@qbit, see https://cs.opensource.google/go/x/build/+/master:env/openbsd-amd64/README. You'll likely need someone on @golang/release to help with deployment.
