After CL https://go-review.googlesource.com/c/37520/ checked in, there are a couple of failures on the build dashboard. The failures are mostly related to finalizers, but may also include others like wrong number of goroutines. For example:
The failure is sporadic.
The linux-mips64le builder is single core. I wonder whether the other two builders are also single core. Not sure whether this is related.
I think freebsd-arm is unrelated to CL 37520. It's been failing pretty regularly since mid-January (fdde7ba).
The other two look real. My hunch is that TestNumGoroutine is a cascade from the others. I don't have a hunch why the first three are failing.
No luck so far reproducing with
This one happens frequently on the android/arm builder:
I can reproduce it fairly quickly with
GOOS=android GOARCH=arm go test -short -cpu=1,2,4 runtime
is there anything I can do to help?
