Hi Bernhard,
In a gnulib testdir, I now see this warning:
In file included from ../../gltests/test-verify.c:22:0:
../../gltests/test-verify.c: In function ‘main’:
../../gltests/../gllib/verify.h:316:25: warning: ‘((unsigned char*)&s)[0]’ is
used uninitialized in this function [-Wuninitialized]
# define assume(R) ((R) ? (void) 0 : __builtin_unreachable ())
^
../../gltests/test-verify.c:115:9: note: ‘s’ was declared here
state s;
^
This is with gcc-5.4.0 and CPPFLAGS="-Wall".
