This looks like it's the same issue as #45040.

[heschi]

Thanks. In that case I think it'd make sense to change the test to either retry or skip the test when this error shows up.

I think CL https://go-review.git.corp.google.com/c/go/+/425355 addressed this? (By checking the C compiler version)

The failures are on Aug. 24 or earlier. The CL is submitted on Aug. 25.

Great, thank you.

Duplicate of #54645.
