Description

Something in the latest win22 image (win22/20220626.1) is causing a regression. This is not seen with the previous image (win22/20220614.0).

The errors seen are of the form

==5248==ERROR: ThreadSanitizer failed to allocate 0x0000019b9000 (26972160) bytes at 0x200d965c00000 (error code: 87)

while running

go test -v ./... -race -coverprofile=coverage.txt -covermode=atomic

Something similar has been seen by other people, and I suspect the cause is the same: tailscale/tailscale#4926, gobuffalo/.github#2

Is it regression?

yes

Expected behavior

the build to pass, or at least to fail for reasons under our control
