Bug #: 54104
Summary: no default argument for 'XXX'
Classification: Unclassified
Product: gcc
Version: 4.7.1
Status: UNCONFIRMED
Severity: critical
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
The following piece of code doesn't compile under gcc 4.7.1 with flag
-std=gnu++11:
template <typename T> struct X {};
template <template <typename T> class P = X, typename U>
void f(const U& m) {
auto g = [] () {};
}
Clang accepts it correctly.
If I remove the line `auto g=...', it compiles successfully.
I am not an expert to standard. So can anyone take a look, and confirm whether
it is a bug of clang or a bug of gcc? Thanks.
