            Bug ID: 102053
           Summary: Invalid syntax of destructor call .~auto is accepted
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: fchelnokov at gmail dot com
  Target Milestone: ---

This program with explicit destructor call is invalid:
```
int x = 1;
int main() { x.~auto(); }
```
because of non-standard .~auto, but G++ accepts it.
