Bug ID: 65075
Summary: [5 Regression] constexpr regression
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: jakub at gcc dot gnu.org
typedef void (*E) ();
template <class T>
constexpr E
bar ()
{
return []() {};
}
void
foo ()
{
(bar<int> ()) ();
}
is rejected since r215954 aka PR55250 with -std=c++11:
error: body of constexpr function ‘constexpr void (* bar())() [with T = int; E
= void (*)()]’ not a return-statement
The body is a return statement, just perhaps with some extra artificial
statements created for the lambda.
