What version of Go are you using (go version)?

go1.8

What operating system and processor architecture are you using (go env)?

GOARM=7 GOARCH=arm

I see a SIGSEGV in sigtrampgo, on line 276:

if sp < g.m.gsignal.stack.lo || sp >= g.m.gsignal.stack.hi {

The relevant disassembly from gdb is

   ldr r2, [r10, #24]
=> ldr r3, [r2, #44]

On that line, gdb says r2 is 0. (r10 is g, so r2 is g.m)

Maybe a dup of #10534?

We can reproduce this very consistently when the cpu profiler is turned on.
