Observed once in a TryBot run on CL 420675:

exit status 0xc0000005
FAIL	runtime	18.548s

(https://storage.googleapis.com/go-build-log/1d5e997e/windows-386-2012_858cca10.log)

Searching around doesn't find this particular exit code, though there are similar ones like in issue #41450. That exit code seems to be a pretty generic "Application Error" failure, so given the rare occurrence maybe there's not much that can be done.

CC @golang/runtime.

I think that error code is specifically a segfault, likely an unrecoverable one (maybe in the win32 libraries or something). We should look into this. How rare is the failure? Is this the only one?

It's the only one I've seen so far; we can try greplogs or similar tools to look if there've been more.

This is a failure similar to #52647. I'm not sure if it is related to this.

Also on https://storage.googleapis.com/go-build-log/4f5c3361/windows-386-2012_1b7a5237.log for https://go-review.googlesource.com/c/go/+/412555, a small change in go/printer:

            > go list -deps -f '{{.Module}}' ./subpkg
            [exit status 0xc0000005]
            FAIL: testdata\script\mod_symlink.txt:10: unexpected command failure
