Bug #: 50261
Summary: [c++0x] ICE on brace-initialize an array member
Classification: Unclassified
Product: gcc
Version: 4.6.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
An ICE occurs with this code:
template <typename T>
struct ca {
T elem[1];
// ICE occurs ...
ca(const T (&s)[1]): elem{{s}} { } // here
//ca(const T (&s)[1]): elem({{s}}) { } // or here.
//ca(const T (&s)[1]): elem(s) { } // but not here (rejects correctly.)
//ca(const T (&s)[1]): elem{s} { } // also rejects correctly.
// also occurs ...
ca(const T &v): elem{{v}} { } // here
//ca(const T &v): elem{{{v}}} { } // and here, or more braces.
//ca(const T &v): elem{v} { } // pass.
//ca(const T &v): elem({v}) { } // pass (with warning).
};
int main() {
int a[1] = {0};
ca<int> d(a);
ca<int> e(a[0]);
}
causes:
test.cc: In instantiation of 'ca<T>::ca(const T (&)[1]) [with T = int]':
