--- Comment #3 from Martin Sebor <msebor at gcc dot gnu.org> ---
GCC rejects the code when the struct has a name:

$ cat t.C && gcc -S -Wall -Wextra t.C
struct S {
    int mem [ ] ;
    int b ;
} s = {1};
t.C:2:9: error: flexible array member ‘S::mem’ not at end of ‘struct S’
    2 |     int mem [ ] ;
      |         ^~~
t.C:4:9: warning: missing initializer for member ‘S::b’
[-Wmissing-field-initializers]
    4 | } s = {1};
      |         ^
