test: add test case that gccgo failed to link Gccgo creates a struct to hold the arguments for the deferred function. In this example the struct holds a type defined in a different package. The bug was that gccgo tried to create an equality function for this struct, and it implemented that function by calling the equality function for the type defined in the other package. Since that type is not exported, the reference to the equality function failed at link time. Normally it is impossible for a struct to directly contain a member that is an unexported type from another package, but in this specific case it was possible. Fixed in gccgo with https://codereview.appspot.com/183500043 .
