Bug ID: 84026
Summary: invalid 'unnamed scoped enum is not allowed' when
scoped enum has a full qualified-id
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: smw at gcc dot gnu.org
Target Milestone: ---
On GCC (all versions tested, up to and including 8.0.1 20180117 with -std=c++14
-pedantic) but not o nMSVC, ICC, or clang, the following code
struct S1 {
enum class E1;
};
enum class S1::E1 {}; // OK
struct S2 {
enum class E2;
};
enum class ::S1::E1 {}; // Not OK
spits out the following error.
9 : <source>:9:16: error: unnamed scoped enum is not allowed
enum class ::S1::E1 {}; // Not OK
^~
9 : <source>:9:10: warning: elaborated-type-specifier for a scoped enum must
not use the 'class' keyword
enum class ::S1::E1 {}; // Not OK
~~~~ ^~~~~
-----
9 : <source>:9:25: error: expected unqualified-id before '{' token
enum class ::S1::E1 {}; // Not OK
^
Looks like it's not quite parsing correctly.
