--- Comment #1 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
Let's note that this issue breaks bootstrap on GCC 5, but it can also be
triggered on any other compiler, including GCC 6 and 7, although for some
reason there it doesn't occur during bootstrap (the libsanitizer code is
different there).

$ cat a.c
#include <CoreFoundation/CFBase.h>
$ gcc-7 a.c 
In file included from a.c:1:0:
/System/Library/Frameworks/CoreFoundation.framework/Headers/CFBase.h: In
