cmd/compile: windows 386 compile crashes

[brydavis]

1. What version of Go are you using (go version)? 1.6.3 x386 (although no issue for older versions like 1.3.3 x386; no issues for 64-bit version of 1.6.3). Unfortunately, circumstances require that I use 32-bit in order to connect to legacy database...
2. What operating system and processor architecture are you using (go env)?
   Windows 64, however I have to use x386 version of Go due to legacy database that is 32-bit
3. What did you do?
   Tried to compile a simple program (like "hello world" simple). Since I don't have admin rights on this machine, had to download / use binary Go compiler. So, I have to build with a command like c:\go\bin\go.exe build. This has worked with previous versions of Go. Here's the error message I get when I try building : go build command-line-arguments: c:\go\pkg\tool\windows_386\compile.exe: exit status 1073741855
4. What did you expect to see?
   No error
5. What did you see instead?
   Using version 1.6:
   go build command-line-arguments: c:\go\pkg\tool\windows_386\compile.exe: exit status 1073741855

Take away: There is some issue with Windows x386 version that did not exist previously. Thanks!

Can you try using the 64-bit compiler to make a 32-bit binary? Set the GOARCH environment variable to 386 before invoking go build.

Marking as Go1.8 since this is not a regression in 1.7.

[quentinmit]

Also, can you please provide the complete output of the "go env" as the template requests? (Assuming that doesn't itself crash.) Thanks.

SOLUTION

env GOARCH=386 \go\bin\go.exe build or env GOARCH=386 go build

I tested by recompiling a database app with and without the env GOARCH=386 prefix. (Again, note that I need 32-bit app so it could connect to legacy database). It worked with the prefix! I was able to query the database (an old IBM product... we're migrating next year).

Thanks for the tip, @quentinmit.

Here's the env info too.

set GOARCH=amd64
set GOBIN=
set GOEXE=.exe
set GOHOSTARCH=amd64
set GOHOSTOS=windows
set GOOS=windows
set GOPATH=
set GORACE=
set GOROOT=c:\go
set GOTOOLDIR=c:\go\pkg\tool\windows_amd64
set GO15VENDOREXPERIMENT=1
set CC=gcc
set GOGCCFLAGS=-m64 -mthreads -fmessage-length=0
set CXX=g++
set CGO_ENABLED=1

Closing issue

[quentinmit]

I'm glad the workaround worked for you, but we'd still like to find out if there is something wrong with the 386 Go binaries. Can you see if the 1.7rc6 386 binaries also crash on your machine?

[hirochachacha]

What version of Windows are you using? I could not reproduce it on my Windows 10.

[brydavis]

I'll test if 1.7rc6 works.

Running on Windows 7 Enterprise (64-bit).

Plot thickens...

I downloaded 1.7rc6 386 binaries and attempted to compile a couple programs (both simple and complex). Here' s error message:

go tool: no such tool "compile"

Hope this helps.
