Comment 0 for bug 1794936

We see this kind of error in recent runs of snapd tests when using bionic updating gccgo and current dh-golang 1.34.

Can be run from snapd master checkout with:

spread -v -debug google:ubuntu-18.04-64:tests/unit/gccgo

with the proper configuration.

Error:

These were passing until today.

Seems related/similar to https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=907263

which mentions dh-golang 1.35 having a fix.
