No idea, all I know is that it happens with ccache and not without. I
don't know if it is a ccache bug, a clang bug, or both: but whatever
it is, it happens iff both are present. Also see e.g discussion with
Ronald on getting av_uninit to clang: we can't do it yet due to ccache
bugs. That reminds me - I still need to file a ticket for it, but it
is low priority for me due to my own favored usage of gcc.
