--- Comment #6 from Martin Jambor <jamborm at gcc dot gnu.org> ---
I am about to test the following, which fixes the test from comment
#1. It does fix a clear bug in the patch I committed today, without
it there we multitudes of identical cgraph duplication hooks active at
the same time.
What worries me is that I cannot ggc_free the memory the structure
sits on without getting a seemingly random segfault later. But
yesterday the structure was not allocated from GC and was freed here,
so its address shouldn't really escape anywhere...
