Hi Florian,

I get the following warning / werror with gcc 4.8.5 on s390x:
gcc tst-dynarray.c -O3 -c ... -o <build>/malloc/tst-dynarray.o
In file included from tst-dynarray.c:50:0:

         ^
tst-dynarray.c:377:23: note: ‘result.length’ was declared here
      struct long_array result;
                        ^

Have you seen those warnings on other architectures, too?

Bye.
Stefan
