            Bug ID: 96452
           Summary: Narrowing conversion is not rejected
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Keywords: accepts-invalid
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: antoshkka at gmail dot com
  Target Milestone: ---

Consider the example:

float test_main(double d) {
    float f2{d};
    return f2;
}


Narrowing of double to float in brace-init is not rejected, only a warning is
issued.
