The sigaltstack fix is now in master (commit 5bfce0b74fbd5d530) and at least in my test environment this also fixes the "can't build hello.go reliably" example. So I'm marking this as 'fix committed'. If there are still problems with running Go binaries, these are likely to be independent bugs, so please open fresh LP issues for them.

This works ok natively but when run under ARM user emulation it segfaults (usually, there are occasionally other failures).
