Public bug reported:
With gcc-6 6.1.1-11ubuntu11:
$ echo '#include <atomic>' > foo.h
$ gcc -fdump-translation-unit -fkeep-inline-functions -c -x c++-header
-fpermissive -w -fPIC foo.h
In file included from /usr/include/c++/6/atomic:41:0,
from foo.h:1:
/usr/include/c++/6/bits/atomic_base.h: In member function
'std::atomic<bool>::operator bool() const':
/usr/include/c++/6/bits/atomic_base.h:390:7: error: inlining failed in call to
always_inline 'std::__atomic_base<_IntTp>::__int_type
std::__atomic_base<_IntTp>::load(std::memory_order) const noexcept [with _ITp =
bool; std::__atomic_base<_IntTp>::__int_type = bool; std::memory_order =
std::memory_order]': function body not available
load(memory_order __m = memory_order_seq_cst) const noexcept
^~~~
In file included from foo.h:1:0:
/usr/include/c++/6/atomic:81:27: note: called from here
{ return _M_base.load(); }

Expected no errors, and translation unit dumped as before, as was with gcc
5.4.0-6ubuntu1:
$ gcc -std=c++11 -fdump-translation-unit -fkeep-inline-functions -c -x
c++-header -fpermissive -w -fPIC foo.h
