runtime/cgo(.text): unknown symbol __stack_chk_fail_local in pcrel (regression in 1.19 when building for i686)

[kanavin]

1.19 no longer builds for i686 targets (where 1.18 was working fine):

CGO_CFLAGS=-fno-stack-protector is a workaround.

Please fill out the issue template. Or at least tell us your GOOS and GOARCH values. Thanks.

It's caused by C flags -fstack-protector-strong

go build works, but go test fails.

-fstack-protector-strong works on go1.18.

Apologies. Does the above clarify matters?

@kanavin Thanks. Does https://go.dev/cl/421935 fix the problem for you?

Change https://go.dev/cl/421935 mentions this issue: runtime/cgo: add -fno-stack-protector to CFLAGS

Thanks, it does.
