Bug ID: 91849
Summary: Misleading diagnostic message when binding reference
to unrelated type
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
void
g ()
{
float f = 1.f;
int &r = f;
}
void
g2 ()
{
int &r = 1.f;
}
gives
q.C: In function ‘void g()’:
q.C:5:12: error: cannot bind non-const lvalue reference of type ‘int&’ to an
rvalue of type ‘int’
5 | int &r = f;
| ^
q.C: In function ‘void g2()’:
q.C:11:12: error: cannot bind non-const lvalue reference of type ‘int&’ to an
rvalue of type ‘int’
11 | int &r = 1.f;
| ^~~
which could be improved. clang++ says
q.C:5:8: error: non-const lvalue reference to type 'int' cannot bind to a value
of
unrelated type 'float'
int &r = f;
^ ~
q.C:11:8: error: non-const lvalue reference to type 'int' cannot bind to a
temporary of
type 'float'
int &r = 1.f;
^ ~~~
