Hi,
I've found the problems. That's because I'm using zsh instead of bash.
After I switched to bash, everything works fine.
Maybe there's some behaviour difference between zsh and bash, but I'm
not familiar with the shells, thus not able to fix them.
I've submitted a CL for
this: https://go-review.googlesource.com/c/gollvm/+/366097
