I have the problem on mac M1 when I use pprof .

Does the problem still exist in the M1 optimized 1.16 release candidate?

[ALTree]

As @changkun pointed out go1.15 is not supposed to work on the arm64 macs, so please try with the 1.16 release candidate.

[ALTree]

(and it seems that rosetta 2 has issues running the Go runtime, see #42700). In this case let's keep the discussion in that thread.

[cherrymui]

Yes, this is a dup of #42700 (which is actually not a Go bug). Closing. Thanks.
