Reproducer
The following simple program gives a compilation error with clang++, while g++
compiles it with no trouble:
$ cat braced-explicit.cpp
class Foo
{
public:
Foo();
};
class Bar
{
public:
operator Foo() const;
};
Foo a{Bar{}};
Foo b(Bar{});
$ g++ -std=c++11 -Wall -c braced-explicit.cpp
$ clang++ -std=c++11 -Wall -c braced-explicit.cpp -save-temps
braced-explicit.cpp:13:5: error: no matching constructor for initialization of
'Foo'
Foo a{Bar{}};
^~~~~~~~
braced-explicit.cpp:1:7: note: candidate constructor (the implicit copy
constructor) not viable: no known conversion from 'Bar' to 'const Foo &' for
1st argument
class Foo
