go crashes with SIGILL: illegal instruction

[Klenov V]

I've installed go to my old computer (Pintium III) with 'sudo apt-get install golang'.
It crashes every time with the following error message:

$go version

Status changed to 'Confirmed' because the bug affects multiple users.

[Michael Hudson-Doyle (mwhudson)]

I think this problem may be fixed in Go git tip by https://go-review.googlesource.com/#/c/15999/ -- is it possible for someone who experiences this bug to try building from Go git? Instructions here: https://golang.org/doc/install/source

[Michael Hudson-Doyle (mwhudson)]

Closing on the assumption that this is fixed in 1.6. Make noise if not.

Is there any chance this is because that CPU lacks sse2? More and more things are being compiled with the assumption that it is available, so any such code will crash on an older processor without it.
