I get this error while running all.bash. It looks similar issue #12814, but as I've got GCC installed, I don't think it is related to Clang. (also, my installed version of Clang is above 3.6). Re-posting this in a separate issue, per Ian's request

[~]$ gcc --version
gcc (GCC) 5.2.0

[~]$ clang --version
clang version 3.7.0 (tags/RELEASE_370/final)

Thread model: posix

[~]$ go version

[~]$ uname -a
Linux x220 4.2.2-1-ARCH #1 SMP PREEMPT Tue Sep 29 22:21:33 CEST 2015 x86_64 GNU/Linux

And the error is as follows:

Must add that I'd never run into this earlier (upgraded recently from ubuntu 15.04 which had gcc 4.9.x and kernel 3.19.0.31).

Relevant output from bash all.bash:

Looks like an upstream issue with LLVM/compiler-rt: https://llvm.org/bugs/show_bug.cgi?id=24155

A fix was pushed earlier this month (Oct 2015), it will likely be shipped with 3.8.0 (no backport to 3.7 given the API breakage). I've proposed a backport for Arch Linux users: https://bugs.archlinux.org/task/46913

I don't see any similar bug for Ubuntu at https://launchpad.net/ubuntu/+source/llvm-toolchain-3.6/+bugs, you could report it if you find it useful. I have not checked whether the patches apply to 3.6 though.

misc/cgo/testsanitizers: check linux major/minor versions
70d558b 
Fix a typo in de5b386; using `$ver` to determine linux major/minor
versions would produce those for clang, use `$linuxver` instead.

Updates #12898.
