1.11

Does this issue reproduce with the latest release?

this is the latest release

What operating system and processor architecture are you using (go env)?

raspbian stretch - up to date kernel as of today
ARM6 and ARM7 - Raspberry Pi B and Raspberry Pi 3B

What did you do?

ran ./all.bash

If possible, provide a recipe for reproducing the error.

Just try compiling the latest version on a Raspberry Pi
Compiled using go1.4

What did you expect to see?

A compiled version of go1.11

What did you see instead?

Building Go bootstrap cmd/go (go_bootstrap) using Go toolchain1.

Bootstrap with Go 1.10 works at least (on Raspberry Pi Model B Plus Rev 1.2, also on Raspbian Stretch), up until I run out of memory:

@bradfitz - I think you may be experiencing #26523.

[bradfitz]

@mooneyr, can you post the full output, starting with ./all.bash or ./make.bash?

Which Go 1.4 are you using?

[bradfitz]

/cc @griesemer too for the "weird decoding" importer error.

[randall77]

This looks like the new binary importer is failing (maybe for the utf8 package?) because the file is corrupted.
Not sure why that would happen.

Never discount that Raspberry Pis eat most SD cards for breakfast.

[mooneyr]

@bradfitz
It's 2 Raspberry Pis with the same problem - it's exceedingly unlikely that it's the sdcard.
It's 3 separate git fetches - I erased and recloned the repo after discovering the first problem - that makes download corruption also unlikely.
I've been compiling every version since 1.6 using 1.4 to bootstrap without this issue until 1.11
using go1.4.1 to bootstrap

complete output follows:

Fair enough. I'm just scarred from many destroyed SD cards over the years.

Where did you get your Go 1.4.1? Did you build it from source on the same Raspberry Pi? Or was it a binary download from somewhere?

[mooneyr]

Where did you get your Go 1.4.1?

I honestly can't remember how I came by it, it was that long ago. All the versions I have on the separate raspberries are the same source though. Guess I can try compiling 1.4 again and try that version to bootstrap 1.11.
I'll also try recompiling 1.10 with the 1.4.1 I have and let you know the results of both.

[mooneyr]

I've recompiled go1.10 using my existing go1.4 to bootstrap, it works.
I've recompiled go1.4 on the Pi3B, that worked.
I've used the newly compiled go1.4 to attempt to compile go1.11 and get the same error as before - weird decoding: 254, true => 129
