I'm trying to cross compile my Go project on windows/amd64 for linux/386, but get a "nosplit stack overflow" error. I followed the instructions that are outlined here. With GOOS=linux and GOARCH=386, my go env looks as follows:
set GOARCH=386
set GOBIN=
set GOEXE=
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=linux
set GOPATH=C:\dev\gopath
set GORACE=
set GOROOT=C:\Go
set GOTOOLDIR=C:\Go\pkg\tool\windows_amd64
set GO15VENDOREXPERIMENT=0
set CC=gcc
set GOGCCFLAGS=-fPIC -m32 -fmessage-length=0
set CXX=g++
set CGO_ENABLED=0
The complete error I get when running go build is:

Other target configurations that do work are GOOS=windows GOARCH=386 and GOOS=linux GOARCH=amd64, but GOOS=linux GOARCH=386 does not work. Any ideas?
