[Bug c++/44585] New: Failure to warn about implicit conversion from double to int

[alvaro dot begue at gmail dot com]

The following code compiles without warning and has an exit value of 1, which
is correct according to the standard. However, an implicit conversion from
double to int happened without a corresponding warning. This seems incorrect to
me, and similar to bug 24525 (
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=24525 ).


struct T {
  double x;
  explicit T(double x) : x(x) {
  }
  operator double() {
return x;
  }
};

T f() {
  return T(5.3);
}

int main() {
  double t = false ? 0 : f();
  return t == 5.0;
}

I just learned about -Wconversion and gcc does indeed warn about the implicit
conversion from double to int when I specify it. Sorry for the false alarm.
