<pre>For the source:
#include <initializer_list>
typedef std::initializer_list<bool> T;
struct A {
A(T) {}
};
void f() {
T x;
A y = {x};
}
in r224592 we used to get with -ast-print for last function:
void f() {
T x;
A y = { x };
}
in r227424 we get:
void f() {
T x;
A y = { { { x } } };
}
The difference comes from different AST, r224592:
`-DeclStmt 0x72db9a8 <line:10:3, col:12>
`-VarDecl 0x72db1d0 <col:3, col:11> col:5 y 'struct A' cinit

`-CXXConstructExpr 0x72db818 <col:10> 'T':'class
std::initializer_list<_Bool>' 'void (const class
std::initializer_list<_Bool> &) noexcept'
`-ImplicitCastExpr 0x72db640 <col:10> 'const class

`-DeclRefExpr 0x72db228 <col:10> 'T':'class
