Title:
golang calls to exec crash user emulation
Status in QEMU:
Fix Committed
Bug
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
The 'qemucrash' test case problem seems to be because we were
incorrectly implementing 'sigaltstack' as setting a process-wide signal
stack. This is incorrect, as sigaltstack stacks are supposed to be per-
thread, and the Go runtime relies on this. I've just sent a patch which
seems to me to fix
The 'qemucrash' test case from this bug still crashes as of current
head-of-git (4.1 rc1).

Observed the same here... (details of the environment at the end of the
post)
Just building a hello world is good enough to crash go 3 times out of 4:
--8<-
ubuntu@qemu:~$ cat < hello.go
> package main

> import "fmt"
