[pkg-go] Bug#856112: acbuild: acbuild run generates garbage on stdout

[Tollef Fog Heen]

Package: acbuild
Version: 0.4.0+dfsg-1
Severity: important

It looks like acbuild run -- command will generate garbage on
stdout (and sometimes just a lot of extra null bytes:

>From an acbuild run, command is acbuild run -- id -u es | hexdump -C:

+ acbuild run -- id -u es                                                     
+ hexdump -C

It's reproducible using echo too:
