--- Comment #6 from Marco Clemencic <marco.clemencic at gmail dot com> ---
I seem to be stumbling on more and more of these spurious warnings.

The latest one is from a header that is found in a directory added to the
search path with "-isystem", and in all cases the warnings talk about metho=
ds
and functions that are "inlined from ...".

I didn't manage to produce a minimal test case proving it, but I start
suspecting that "-isystem" is ignored (in some circumstances) when functions
get inlined.=
