C++ code model does not recognize typed enums

Since 15.0.1 update, typed enums are no more recognized by code model. The declaration is underlined in red with the tooltip "unexpected token ':' ".
The result is that the enum and it members are not referenced and cannot be "followed".

When there is two successive enums, the second is underlined in yellow with the tooltip "extra ';'"

Sometimes, there is no underline at all, but in all cases, the enum and its members are not referenced in the code model.
