  • It might be helpful to know:
    • Does the exact same program run fine on a non-windows OS?
    • Does the exact same program run fine on a windows amd64 OS?
    • Is the program using CGO at all (I looked briefly and think the answer is no)?

Please ask on golang-nuts how to debug this problem.
It is normally a bug in the user code, for example, saving
an integer in a pointer, esp. code that is using cgo.
(one example that affects windows code particularly is that
although HANDLE is a pointer type, windows actually stores
integers into it and if you store HANDLE on Go stack or
heap, it will trigger this error.)

If you don't want to find the bug, you can temporarily
disable the invalid pointer check by setting GODEBUG=invalidptr=0,
however, as documented in Go 1.4 release note
(http://golang.org/doc/go1.4#runtime), we don't guarantee
that the invalid check can be disabled in future Go releases,
so it is still recommended to fix such problems with Go 1.4.

We had 4 reports on this, 3 out of 4 times it was Windows 32bit, the 4th was some storage device:
syncthing/syncthing#1280 but I don't have stack traces for Go 1.4.1.

No CGO involved as far as I know.

Is it obvious from the traces which routine the invalid pointer is found?

The pointer is encountered during GC, so it's hard to say where does the
invalid pointer come from.

Normally the GC will also print one line of the form:
runtime: garbage collector found invalid heap pointer *(addr+offset)=addr

before the panic. That is important clue.

I am closing this for now, will try to figure out where it happens in the code first, as it seems to be 100% reproducible on the machines in question. I have a hunch that it will most likely be caused by using syscall stuff.

There seems to be some interleaving writes, but perhaps this one makes more sense?

This is go 1.4.1 on arm linux, which doesn't use cgo nor any of the syscall stuff excessively.

@AudriusButkevicius, do you have self-contained code to repo this?

Sadly not, as these are all reported in the issue tracker part of the project I am working on. Everyone experiencing this seem to have 100% reproducibility, so doing a simple binary search could pinpoint to the right location.

I'll see if I can get someone to do that for me.

I would make sure that values passed back from Windows, such as HANDLEs,
are not treated as pointers by the Go code if they are actually not
pointers and in fact small integers. This is typically what we have seen
with traces like this.
