  1. What version of Go are you using (go version)?
    gomobile revision c435d0b
  2. What operating system and processor architecture are you using (go env)?
    built on darwin amd64
    executed on ARMv7 android 6
  3. What did you do?
  • Enable pprof via net/http/pprof
  • Start profiling with go tool pprof http://<host>/debug/pprof/profile

This causes the application to exit without any more details than:
Zygote : Process 6268 exited due to signal (27)

The other goroutine & heap profiling works fine.

Is this still a problem? If so, can you verify that profiling a Go library (built with -buildmode=c-shared) run from a C main program works? The result of that experiment will determine whether the problem is with android in particular or with profiling c-shared libraries.
Thank you.
