What did you do?

  1. Run gomobile build -target=ios -bundleid=com.hajimehoshi.gomobiletest -work golang.org/x/mobile/example/basic
  2. Open the generated main.xcodeproj
  3. Install it on a device (iPhone 6 in my case)
  4. Run the app via Instruments memory profiler (Zombie)

What did you expect to see?

The app runs without memory increase.

What did you see instead?

The memory usage is increased monotonically:

Screenshot from Gyazo

It looks like _IOAccelResourceAlloc allocates memory and it is never disposed? I'm not sure this is an actual leak.
