           Summary: 64 bit codegen bug involving dynamically indexed
                    static array and continue statement
           Product: D
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com
        ReportedBy: timon.gehr gmx.ch

DMD 2.059
void main() {
    int i = 0;
    int[2] a;
    a[1]=1;
    while(!a[0]){
        if(a[i]) continue;
        a[i] = 1;
    }
}

The code terminates with -m32 and enters an infinite loop with -m64.
No other flags are necessary to reproduce.

In windows with -m64 dmd 2.060 produces Internal error: ..\ztc\cgobj.c 1479

I could not reproduce it with the current build, but I added it to the test
suite anyway,
