Panic when running

[mvrhov]

I got the panic bellow on two projects.
Now both of those projects use cgo and a modules in private repositories in go.mod. Bu I'm pretty sure that the modules in private repositories are at fault as I have another project without cgo but with modules in private repository.

panic: runtime error: invalid memory address or nil pointer dereference
