Bug #: 53484
Summary: [c++11] Wrong auto in lambdas in function templates
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org
ReportedBy: omawarisan.bokud...@live.jp
In the following program, auto is deduced to be int&, while int is expected.
template <class T>
void f(T x){
[&]{
std::cout << x << std::endl;
auto y = x;
y = 100;
std::cout << x << std::endl;
}();
}
int main(){ f(0); }
output:
0
100
In non-template functions, it doesn't occur.
