I took the preprocessor output of one of the moc_*.cpp files and find
that it comes down to something like this:
struct A {
int a;
A(int value) : a(value) {}
};
struct S {
A a;
};
S s { { -1 } }; // error
A a { -1 }; // OK
A aa( -1 ); // OK
Error with Clang 3.1:
error: initialization of non-aggregate type 'A' with an initializer list
S s { { -1 } };
^~~~~~
It seems the added constructor is confusing Clang. The same code
compiles fine with GCC 4.7.
In Qt 5's case. A is QBasicAtomicInt and S is QtPrivate::RefCount. If
that makes sense.
