Bug ID: 42778
Summary: Cannot aggregate initialize with C++17 *this lambda
capture
Product: clang
Version: unspecified
Hardware: PC
OS: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++17
Assignee: unassignedclangb...@nondot.org
Reporter: romain.geiss...@amadeus.com

Hi,
The following snippet triggers a compiler error with -std=gnu++17:
<<END_OF_FILE
#include <functional>
struct A
{
std::function<void()> function;
void f() {};
};
struct B
{
void f()
{
A{[*this](){}}.f();
}
};
END_OF_FILE
It fails with:
<source>:14:18: warning: use of GNU 'missing =' extension in designator
[-Wgnu-designator]
A{[*this](){}}.f();
^
=
<source>:14:19: error: expected expression
A{[*this](){}}.f();
^
<source>:14:12: error: integral constant expression must have integral or
unscoped enumeration type, not 'B'
A{[*this](){}}.f();
^~~~~
1 warning and 2 errors generated.
Compiler returned: 1
tested with clang 8, 9 and current HEAD: https://godbolt.org/z/gVhxD3 Gcc 9 is
happy with that.
