go: cmd/compile: fatal error: runtime: cannot map pages in arena address space

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.

TL;DR: For cmd/compile, this is a dup of #16394, which @mdempsky fixed in November (thanks!). For cmd/vet (really go/types), there is a new problem, for which I will file an issue and fix for Go 1.10. There is also a minor cmd/gofmt issue for Go 1.11, which I will file.

For the older releases I also sent a PR for go-bindata to emit balanced trees and also a PR to ethereum to use that go-bindata. Those are linked above and will fix the problems with older toolchains and ethereum. (Thanks @kevinburke and @karalabe.)

go get -u rsc.io/tmp/bigprog is a simple test of how our tools handle long arithmetic expressions like 1 + 1 + 1 + 1 + … + 1 or “1” + “1” + “1” + “1” + … + “1”, compared with balanced expressions like ((“1” + “1”) + (“1” + “1”)), inspired by the problem in #23222, which involved a string concatenation of about 700 strings. To run it, also do go get -u golang.org/x/tools/cmd/gotype.

The results on my 2015 Mac laptop, in both 64-bit and 32-bit mode, are below. This line:

      1000  int   0.019s  strbal   0.021s  strbigbal   0.037s  str   0.025s  strbig    0.032s

means that a tool was run on five different programs each with a single expression containing 1000 addition operations.

The int program is 1 + 1 + 1 + … + 1. The str program (later in the line) is “1” + “1” + “1” + … + “1”. The strbig program is str but each literal is actually 1000 1 characters: “111…1”. The strbal and strbigbal programs are str and strbig but add parentheses to make a balanced parse tree. Note that the tables report strbal and strbigbal before str and strbig, because strbig in particular is the worst case for many tools.

The compiler does very well, because Matthew fixed this in the parser to address #16394, in https://golang.org/cl/76450, during the Go 1.10 cycle. The reports of stack overflow in the Go 1.9.2 compiler are essentially dups of #16394, now fixed. Even before that change, the compiler needed stack to recurse over the whole expression but otherwise handled it efficiently, with a single allocation to construct the whole concatenation (I did that in 2014, mainly to speed program execution, but it had the effect of speeding compilation too (https://golang.org/cl/83090046)). With Matthew’s fix, there’s basically nothing left to do in the compiler.

The go/types package does not do as well, because it does not have the OADDSTR optimization in typecheck, nor in the parser. When go/constant builds up the actual value of the expression, it is accidentally quadratic on str: it allocates “1”, then “11”, then “111”, then “1111”, and so on. Similarly for strbig, with longer strings. On my Mac, a 32-bit gotype runs out of memory in a concatenation of 4000 1k strings (4MB total). On strbal and strbigbal it does better: the balanced tree makes it accidntally O(n log n). Luckily the go/constant API is well enough designed that the underlying representation can be changed to do the actual concatenation lazily, cutting it back to O(n) even on the unbalanced case. This is important to fix because the new automatic go vet uses go/types. I will file a new issue and send a CL for that, for Go 1.10.

Finally gofmt. I ran gofmt originally as a control, thinking that comparing to gotype would let us see how much time was spent in typechecking (gotype minus gofmt). Unfortunately, gofmt itself seems to have some accidentally quadratic behavior in making its layout decisions. (I won’t be surprised if the problem is in the code to decide whether to add spaces around operators, which would make it my fault, and if so, my apologies). I will file a Go 1.11 issue for gofmt.
