Bug ID: 114315 Summary: Attributes should be diagnosed when placed in the middle of declaration specifiers Product: gcc Version: 14.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: c++ Assignee: unassigned at gcc dot gnu.org Reporter: luigighiron at gmail dot com Target Milestone: --- GCC will accept programs that use attribute specifiers in the middle of declaration specifiers, for example: int[[]]signed main(){} Attribute specifiers are not allowed inside of the declaration specifiers. I would expect a warning or an error here, at least when -pedantic/-pedantic-errors. Here is a link to the grammar of declaration specifiers: https://eel.is/c++draft/dcl.spec.general#nt:decl-specifier-seq. The attribute specifier is required to be at the end of the declaration specifiers.
