when I install from sources straight from git checkout go1.7rc6
go1.7rc6 FAILS on Asus Z97-A-USB31 motherboard with intel i5-4590,
it core dumps and doesn't give me the success message to start using it as the previous go1.7rc[1-4] did.
signal: segmentation fault (core dumped)
FAIL: msan
FAIL: msan2
FAIL: msan3
FAIL: msan4

To contrast this, Go1.7rc6 does succeed on another much older motherboard Dell Inc. Vostro 430/054KM3, BIOS 2.2.0.

Ok so yes I recently installed clang on this archlinux box.  The previous go binaries were built with gcc/g++.

So to clarify and save others time:

1)to build using gcc/g++:
CC=/usr/bin/gcc CXX=/usr/bin/g++ GOROOT_BOOTSTRAP=/root/go1.7rc5 ./make.bash

2)to build using clang/clang++:
CC=/usr/bin/clang CXX=/usr/bin/clang++ GOROOT_BOOTSTRAP=/root/go1.7rc5 ./make.bash

By explicitly setting those CC and CXX variables, I was able to revert to my original gcc/g++ built golang binaries in order to be consistent since my earlier binaries were built with gcc/g++ I prefer to stay on that path for the moment.

Hi David,

The issue you are having seems related to https://github.com/golang/go/issues/16636

I'm also running Arch Linux, and it seems like -fsanitize=memory is broken on general for Clang on Arch. Would you be able to verify if this is also the case for you? Add a comment to the issue, rather than this thread to keep the discussion on track.

Cheers /u
