Hi Jessica,
we've had a bug in our resolution of _GPL modules since day one, that is a module can claim to be GPL licensed and use _GPL exports, while it also depends on symbols from non-GPL modules. This is used as a circumvention of the _GPL exports by using a small shim module using the _GPL exports and the other functionality. A recent example can be found here:
