<pre>For the code
struct A
{
explicit operator bool() { return true; }
};
int main()
{
A a;
bool b { a }; // BUG or Error here??
}
I have error:
error: no viable conversion from 'A' to 'bool'
but part 12.3.2.2 of the C++11 standard states that "explicit operator bool()"
will be (and must be) used in the direct initialization, and according to the
part 8.5.15 of the C++11 standard "bool b{a}" is a direct initialization of the
b. So is it a bug or I miss something?
GCC 4.8.2 accept such code without error.
I use clang++ under Mac OS X (clang++ --version says: Apple LLVM version 5.0
(clang-500.2.79) (based on LLVM 3.3svn))</pre>
