digitalmars.D.bugs - [Issue 21043] New: Diagnostic for autogenerated opAssign needs to


          Issue ID: 21043
           Summary: Diagnostic for autogenerated opAssign needs to improve
           Product: D
           Version: D2
          Hardware: x86
                OS: All
            Status: NEW
          Severity: minor
          Priority: P1
         Component: dmd

struct S
    ~this () { }

void main ()  safe
    S[int] map;
    map[1] = S.init;

$ dmd test.d
 test.d(9): Error:  safe function D main cannot call  system generated function
 test.d(1):        test.S.opAssign is declared here
This doesn't actually say where the problem is. The issue is the system destructor. Marking that destructor safe solves the issue. Maybe the diagnostic should say that. --
