Thanks for the report.

Have you tried CGO_CFLAGS=-fno-stack-protector as a workaround, just to confirm?

[aarzilli]

It does work.

[thanm]

OK, thanks. Sounds like we need another CL similar to 421935, but with wider scope.

Not sure about the best way to fix this; sent two possible CLs.

Change https://go.dev/cl/466935 mentions this issue: cmd/cgo: add -fno-stack-protector to CFLAGS (again)
