Bug #: 50169 Summary: "new struct X {{}};" incorrectly treated as an invalid struct-definition Classification: Unclassified Product: gcc Version: 4.7.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ AssignedTo: unassig...@gcc.gnu.org ReportedBy: schaub.johan...@googlemail.com The following looks like valid code: struct A { int a; }; int main() { new struct A {{ }}; } The type-specifier-seq "struct A" is followed by a braced-init-list "{{}}". But GCC says: main1.cpp: In function 'int main()': main1.cpp:3:16: error: types may not be defined in a new-type-id main1.cpp:3:17: error: expected unqualified-id before '{' token As far as I can see, I would only define a new type if I would say: new struct A { }; But the two-braces disambiguates it.
