* [Bug c++/30836] New: template T[] doesn't catch T[5] @ 2007-02-17 17:49 igodard at pacbell dot net 2007-02-17 19:11 ` [Bug c++/30836] " igodard at pacbell dot net ` (2 more replies) 0 siblings, 3 replies; 4+ messages in thread From: igodard at pacbell dot net @ 2007-02-17 17:49 UTC (permalink / raw) To: gcc-bugs The code: #include <iostream> template<typename T> struct foo { static const int i = 0; }; template<> template<typename U> struct foo<U[]> { static const int i = 1; }; int main() { int v[5]; std::cerr << foo<int[5]>::i << ":" << foo<int[]>::i << "\n"; return 0; } prints: 0:1 which shows that int[5] is not caught by a T[] specialization. This may be the standard, but I'm not sure and submit it anyway in case it's a bug. -- Summary: template T[] doesn't catch T[5] Product: gcc Version: 4.1.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: igodard at pacbell dot net http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30836 ^ permalink raw reply [flat|nested] 4+ messages in thread

I know I can catch it with: template<> template<Type T, size_t N> struct foo<T[N]> {...} but I though that plain "[]" would catch it too. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30836 ^ permalink raw reply [flat|nested] 4+ messages in thread

And we are all implementing the is_array trait with 2 specializations (Vandevoorde and Josuttis included in their book). -- pcarlini at suse dot de changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED Resolution| |INVALID http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30836 ^ permalink raw reply [flat|nested] 4+ messages in thread
