     This is an interesting one that has cropped up. I'm curious if
this is because the differences between a fixed/dynamic arrays.
Working around it is easy enough but that it even does it is an

     I'm not seeing this exact problem in the archives, and I am 
sure if it's in the tracker already under a different
name/identifier. :(

module internal_error_485;
/*Internal error: ..\ztc\cod3.c 485
      happens when class (or inherited) have one return a string 
convert) and the other with the workaround.

      Oddly it isn't doing auto conversion/shortening on a string 
a known size.

alias immutable(char[4]) string4;
class x {
      string4 f() {
//      return cast(string4) "HEDR";    //Internal error:
..\ztc\cod3.c 485
//      return cast(string4) "HEDR".ptr;  //same

//      return "HEDR";      //implicit conversion fails
//      return string4("HEDR");  //temporary object doesn't
create properly for returning.

          string4 x = "HEDR";
          return x;

class z : x {
      override string4 f() {
        return "brk_";  //Internal error: ..\ztc\cod3.c 485
//    return cast(string4) "brk_";  //Same error

//    following works... but...
//    string4 x = "brk_";
//    return x;


     it also breaks the same way if the base class returns the
and the inherited class returns the converted/long steps.

Maybe... but it shouldn't be the wrong return; at least being a static length known at compile-time should convert to char[4]. I'm not sure how try/catch would make a difference either. But being as making a temporary to get the compiler to work around it means it isn't a critical problem. If these are related though, I could post my code there they are breaking at different points.
