Bug ID: 61022
Summary: [C++11] Bogus "error: parameter packs not expanded
with '...'"
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: ppluzhnikov at google dot com
Google ref: b/14441040
// --- cut ---
template <typename T> struct Template {};
template <typename O> struct TemplateAliasStruct {
template <typename T> using TemplateAlias = Template<T>;
};
template <template <typename> class... T> struct Templates {};
// Using this alternate definition of Templates compiles:
// template <template <typename> class... W> void Templates() {}
template <typename... W>
void DoTest() {
Templates<TemplateAliasStruct<W>::template TemplateAlias...>();
}
int main(int argc, char* argv[]) {
DoTest<int, int>();
return 0;
}
// --- cut ---
Using trunk @r209848:
g++ -c -std=c++11 t.cc
t.cc: In function 'void DoTest()':
t.cc:14:65: error: parameter packs not expanded with '...':
Templates<TemplateAliasStruct<W>::template TemplateAlias...>();
^
t.cc:14:65: note: 'W'
The test compiles cleanly with Clang.
