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:
