Can somebody check this, please?

//------------------------------
import std.string;
import std.stdio;

void main()
{
    char [] str1="sus mejores cortesanos. Se embarcaron en el puerto de Dubai y";
    char [] str2="page-break-before";
    writefln(ifind(str1,str2));
}
//------------------------------

The output I'm getting (DMD 0.112, WinXP Pro SP2) is (roll drums....) 45, when it should be -1. Why it's happening, I have no idea. find, rfind, irfind seem to work ok, but not ifind.

Confirmed (DMD v0.112, compiler v0.111, WinXP Pro SP2).

It's a bug in std.string (line 571 - 597.)
My quick fix goes here:

585c585
<                   break;
---
>                   return i;
586a587
>               return -1;
595c596
<                   break;
---
>                   return i;
596a598
>               return -1;

A shorter test case:  assert(ifind("00","01")<0);

BTW, find, rfind, and irfind do not have this bug as far as i see.
