Bug ID: 69673
Summary: Can't pass members in lambda capture list
Product: gcc
Version: 5.3.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: petschy at gmail dot com
Target Milestone: ---
struct A
{
int i;
};
void foo(A& a)
{
auto l = [&a.i]() { };
}
void bar(A& a)
{
auto& i = a.i;
auto l = [&i]() { };
}
void baz()
{
A a;
auto l = [&a.i]() { };
}
---8<---8<---8<---
Only bar() compiles, the other two functions fail :
g++-5.3.1 -std=c++11 20160204-lambda.cpp
error: expected ‘,’ before ‘.’ token
auto l = [&a.i]() { };
^
Every gcc version I tried failed: 4.7.4, 4.8.4, 4.9.2, 5.3.1, 6.0.0
g++-5.3.1 -v
Using built-in specs.
