garble: Error during garble build

I’m trying to build my go app binary on MacOs, but build fails with error:

/usr/local/Cellar/go/1.15.5/libexec/pkg/tool/darwin_amd64/link: running clang failed: exit status 1
Undefined symbols for architecture x86_64:

I tried to build it with GOARCH=arm GOOS=linux envs, but build failed with another error:

path/to/package is my package. Sorry, can’t write it here)

It is the same project as in this issue: https://github.com/burrowers/garble/issues/202

Error in https://github.com/burrowers/garble/issues/202 issue seems like fixed, but as you can see new one appeared.

I’m using currently lates revision: https://github.com/burrowers/garble/commit/e014f480f99974a2976166fe5252fc41676a598a
