[Bug c++/20209] New: [3.3/3.4/4.0 Regression] Missing warnings for "aggregate has a partly bracketed initializer"

[pinskia at gcc dot gnu dot org]

The following should have warnings:
struct S { char a[6]; int b[2]; };

S S0 = { { "hello" }, { 1, 2 } };
S S1 = { { "hello" }, 1, 2 }; // { dg-warning "" }
S S2 = { "hello", { 1, 2 } };
S S3 = { "hello", 1, 2 }; // { dg-warning "" }

Obviously I compiled with "-W -Wall".
I wonder how this regression was missed for so long.

Yeah, caused by addition of reshape_init.
Bigger testcase:

// PR c++/20209
// { dg-do compile }
// { dg-options "-Wmissing-braces" }

struct S { char a[6]; int b[2]; };
struct T { int a; int b[2]; };
struct U { int a; T b; };
struct V { char a[6]; int b[2]; int c; };
struct W { int a; int b[2]; int c; };
struct X { int a; W b; int c; };

S a = { { "hello" }, { 1, 2 } };
S b = { { "hello" }, 1, 2 };    // { dg-warning "" }
S c = { "hello", { 1, 2 } };
S d = { "hello", 1, 2 };        // { dg-warning "" }
T e = { 1, { 2, 3 } };
T f = { 1, 2, 3 };              // { dg-warning "" }
U g = { 1, { 2, { 3, 4 } } };
U h = { 1, 2, { 3, 4 } };       // { dg-warning "" }
U i = { 1, 2, 3, 4 };           // { dg-warning "" }
V j = { { "hello" }, { 1, 2 }, 3 };
V k = { { "hello" }, 1, 2, 3 }; // { dg-warning "" }
V l = { "hello", { 1, 2 }, 3 };
V m = { "hello", 1, 2, 3 };     // { dg-warning "" }
W n = { 1, { 2, 3 }, 4 };
W o = { 1, 2, 3, 4 };           // { dg-warning "" }
X p = { 1, { 2, { 3, 4 }, 5 }, 6 };
X q = { 1, 2, { 3, 4 }, 5, 6 }; // { dg-warning "" }
X r = { 1, 2, 3, 4, 5, 6 };     // { dg-warning "" }
