What version of Go are you using (go version)?

go version go1.9.2 windows/386

Does this issue reproduce with the latest release?

Yes

What did you do?

We've noticed on our CI that 32bit Windows builds started crashing during compilation https://ci.appveyor.com/project/ethereum/go-ethereum/build/master.4791/job/hcsxkgy0uh018j05#L136.

After playing around with it trying to repro locally, we've managed to triage it to the 32bit Windows build of Go. To reproduce the issue yourself:

• Download and install the 32bit version of Go on Windows
• Download and install the 32bit version of MinGW64 on Windows
• Run go get -v github.com/ethereum/go-ethereum/dashboard

The repository is quite large, so downloading it will take a while.

What did you expect to see?

A successful build.

Issue being tracked on the go-ethereum repo too: ethereum/go-ethereum#15738.

[titanous]

Does this also happen with git master, soon to be go1.10?

[karalabe]

We've received a similar crash from a user running Linux (ethereum/go-ethereum#15743), so it seems to be unrelated to Windows itself and may be a general fault on 386. I'll have to check latest master.

[alexbrainman]

I'll have to check latest master.

This works fine for me for recent version of Go:

Go 1.10beta1 blows up on AppVeyor the same way https://ci.appveyor.com/project/ethereum/go-ethereum/build/master.4840/job/y99c2g1ywdho2d34#L264

I'll have to try somehow a master build on AppVeyor to see if it's still present on latest code.

[karalabe]

Managed to reliably reproduce it locally with Go 1.10, both beta1 and latest master. The invocation is a bit different than my repro for Go1.9.2:

@karalabe, can you confirm that adding go test -vet=off fixes it? I think it's the vet checker running in parallel with go test that's consuming a lot of memory.

[karalabe]

Confirmed, -vet=off fixes my above repro.

[bradfitz]

So, I guess go/types is just memory hungry and that hurts on 386's small address space. Presumably we'd have the same problem on arm and other 32-bit platforms.

Optimizing go/types at this point seems too much too late. @griesemer, @alandonovan ... ?

Or is the GC failing us here? @aclements.

Maybe just detect this runtime error from vet and ignore it, as if vet didn't run? @ianlancetaylor, @rsc.

[aclements]

The particular error code is odd. 487 is ERROR_INVALID_ADDRESS, which is not what I'd expect if we just ran out of memory. @alexbrainman, any idea why VirtualAlloc(MEM_COMMIT) would return that, especially given that we must have just successfully called VirutalAlloc(MEM_RESERVE) for the same address, and the addresses all look totally reasonable (e.g., 0x43f20000)?

@karalabe, I wasn't able to make sense of the issue you linked to (ethereum/go-ethereum#15743), since the traceback appears incomplete. Why do think it's related?

[griesemer]

@bradfitz Assuming it's not some other go/types unrelated issue, it would be interesting to see which exact code leads to the problem and if it's always the same. The following patch prints the location and operands before the code goes into go/constant.BinaryOp:

It probably needs to be refined otherwise it prints too much, but it may be a starting point.

(I'm out through 1/1/18 but can try to help after that.)
