What did you do?

When I execute go test -msan as a stage of my pipeline, it sporadically produces "segmentation fault" error and make stage failed. When I spam retry like 3-5 times, then it produces no error and stage can pass in my Gitlab pipeline.

What did you expect to see?

See memory sanitizer test successful.

What did you see instead?
