This seems like the best solution (free and NULL the dev pointer in
dev_Close(), BEFORE GEdestroyDevDesc() has a go).
I think this should be safe because dev_Close() and GEdestroyDevDesc()
are only called in one place (so your free() should always happen before
GEdestroyDevDesc() and your fr
I perused the source for RStudio and noticed that they had a similar
problem. I didn't think that the GEDevDesc structure was exported, but
apparently this is a worthwhile workaround to the defect.
void GD_Close(pDevDesc dev)
{
