What did you do?
The tests for my project, go.elastic.co/apm
, started failing when running against go tip.
I strongly suspect 7fc2625, since it started happening today. The issue can be reproduced with https://play.golang.org/p/MQepDRMdcjL
What did you expect to see?
The program should run and exit cleanly.
What did you see instead?
The program runs for ~10 seconds and panics, due to CancelRequest not being called.
Note that this doesn't happen every time, hence the loop. If I increase the timeout to 50ms it becomes less frequent, but still fails occasionally.
