I upgraded the netbsd/386 builder to the latest 7.0.1 release,
and suddenly a lot of the builds fail at os/signal.

E.g.
timeout:
https://build.golang.org/log/f4c637234824467172beb3c7fdaf61fbd403d55c
illegal instruction:
https://build.golang.org/log/d1841610bb2fd982671f4db6bd8d1836a0a2d735
(this log also shows a failure in runtime/pprof, which might be interesting
as well.)
SIGTRAP:
https://build.golang.org/log/7275a54c64635553b418a15a58475698cf772f64

Repeated run of os/signal tests showed that it's failing in TestStress.

/cc @ianlancetaylor any ideas?

Is that the same as #10027?

See if you can get the strace output (or dtruss, or whatever it is called on NetBSD) of signal.test -test.short -test.run=TestStress.

Sounds like something is going wrong if a signal is received while handling that signal. Or, it's a problem with the alternate signal stack.

If the entire builder VM freezes then it's probably not Go's fault. Sounds like a kernel problem.

The same test error of Go-1.8 On NetBSD/amd64(7.0.1 GENERIC).

Thanks to coypoop for noticing at:

  #22914 (comment)

FreeBSD/386 and NetBSD/386 diverged between Go 1.4 and Go 1.5 when
Russ sent https://golang.org/cl/135830043 (git rev 25f6b02)
to change the calling convention of the C compilers to match Go.
But netbsd wasn't updated.

Tested on a NetBSD/386 VM, since the builders aren't back up yet (due
to this bug)

Fixes #22914
Updates #19339
Updates #20852
Updates #16511

This is fixed by requiring NetBSD 8-BETA+.
