           Summary: Unreachable code in Phobos std.algorithm sort
           Product: D
           Version: 2.026
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Keywords: rejects-valid
          Severity: normal
          Priority: P3
         Component: Phobos
        AssignedTo: bugzilla at digitalmars.com
        ReportedBy: gide at nwawudu.com


The following code does not compile with warnings enabled (-w). Commenting out
src\phobos\std\algorithm.d lines 2119 and 2121 fixes the issue.

import std.algorithm;

void main() {
        int[] a = [1, 2, 3];
        sort(a);
}

C:> dmd -w test.d
warning - C:\D\dmd\windows\bin\..\..\src\phobos\std\algorithm.d(2119): Error:
statement is not reachable
C:\D\dmd\windows\bin\..\..\src\phobos\std\algorithm.d(2504): template instance
