Bug ID: 70352
Summary: [C++11] auto cannot be used in the type-id of a
new-expression
Product: gcc
Version: 6.0
Status: UNCONFIRMED
Severity: trivial
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: kariya_mitsuru at hotmail dot com
Target Milestone: ---
The sample code below should be compiled successfully but it causes a
compilation error.
============== sample code ==============
int main()
{
auto p = new (auto)(42);
}
============== sample code ==============
cf. http://melpon.org/wandbox/permlink/eSIE4OPkAubCIO5z
The C++11 standard 7.1.6.4 [dcl.spec.auto] p.4 says,
The auto type-specifier can also be used in declaring a variable in ...,
in the type-specifier-seq in the new-type-id or type-id of a new-expression
(5.3.4),
...
The 'auto' type-specifier above is a type-id, so it is well-formed.
