<pre>When I attempiting to convert the value which is explicitly convertible to
bool, an odd error occurs.
Below is a code to reproduce it.
class X {
explicit operator bool()
{
return false;
}
};
int main()
{
bool b = {X{}};
return 0;
}
When the code is compiled, below error will be shown.
hoge.cpp:12:10: error: no viable conversion from 'void' to 'bool'
bool b = {X{}};
^ ~~~~~
1 error generated.
where does 'void' come from? I think this error message is incorrect.
I could reproduce this bug with clang 3.4.2 in OS X, clang 3.5.0 in Linux and
clang 3.6.0 (trunk 218519) .
Below link is the output of clang 3.6.0 by online compiler.
