Public bug reported:
Hello!
I figure out that sometimes simple go application is not working.
I am using docker + qemu-arm + go( for armv7l).
These are version info below.
root@VDBS1535:~# docker -v
Docker version 17.09.1-ce, build 19e2cf6
bash-3.2# qemu-arm --version

This issue is come only when I disable core 0 using a command below.
please check "--cpuset-cpus=1-55" option.
sudo docker run --privileged -d -i -t --cpuset-cpus=1-55 --mount
type=bind,source="/home/dw83kim/mnt",destination="/mnt" --network host
--name="ubuntu_core1" ubuntu:xenial-20200212
This is what I have tested in the environment above.
package main
func main(){
for i:=0; i<1000; i++ {
println("Hello world")
}
}
This is one of the error logs have faced sometimes not always.
bash-3.2# go run test.go
fatal error: schedule: holding locks
panic during panic
SIGILL: illegal instruction
PC=0xc9ec4c m=3 sigcode=2
goroutine 122 [runnable]:
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
bash-3.2#
Please check it.
Thanks in advance.
