Bug ID: 92032
Summary: DR 1601 - Promotion of enumeration with fixed
underlying type
Product: gcc
Version: 10.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mpolacek at gcc dot gnu.org
Target Milestone: ---
The following should compile with this DR:
enum E : char { e };
int f(char);
void f(int);
void
g ()
{
int k = f(e);
}
because [over.ics.rank]/4.2:
"A conversion that promotes an enumeration whose underlying type is fixed to
its underlying type is better than one that promotes to the promoted underlying
type, if the two are different."
