            Bug ID: 120755
           Summary: Catching reference to array also catches thrown
                    pointers
           Product: gcc
           Version: 15.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: blubban at gmail dot com
  Target Milestone: ---

int main()
{
    int* var = nullptr;
    try { throw var; }
    catch (int(&)[8]) { return 1; }
    catch (...) { return 0; }
}


Expected: Return 0, and/or throw a compile error or warning about array
references being uncatchable (they decay to pointers if thrown).

Actual: Returns 1, despite nobody throwing a reference to size-8 array.
