Does your program use cgo or SWIG? Does it use unsafe? Have you run your program under the race detector?

I forgot: if I run go test -bench=BenchmarkServerParallelism -benchmem github.com/pierrre/imageserver/cache/groupcache
on Go 1.6.2, it works.

Have you run your program under the race detector?

Yes, go test -race -bench=BenchmarkServerParallelism -benchmem github.com/pierrre/imageserver/cache/groupcache
works on Go 1.6.2

Does your program use cgo or SWIG?

As far as I know, no.

Does it use unsafe?

Not directly.
My program uses groupcache, that uses protobuf, that uses unsafe.
See https://github.com/golang/protobuf/blob/master/proto/pointer_unsafe.go#L40

It's really frustrating, because I don't know what to do to fix this crash.

I tried to enable the "appengine" tags: go test -a -x -tags=appengine -run=NONE -bench=BenchmarkServerParallelism -benchmem github.com/pierrre/imageserver/cache/groupcache
I disables the usage of "unsafe" in protobuf.
But it still crashes.

There is something weird with my imageserver.Image.UnmarshalBinaryNoCopy() method:

  • if I remove all the code (just keep return nil), it doesn't crash
  • if I add return nil at the beginning (keep all the code), it crashes

I don't understand...

We can reliable reproduce this here and are well on our way to root causing it.

We should test the fix for this against the case in #15762, once we have one.

It's fixed for me.
go test -bench=BenchmarkServerParallelism -benchmem github.com/pierrre/imageserver/cache/groupcache
doesn't crash anymore.

Thank you @rsc 👍
