           Summary: BigInt(1)-1 problem
           Product: D
           Version: D2
          Platform: x86
        OS/Version: Windows
            Status: NEW
          Keywords: wrong-code

          Priority: P2
         Component: DMD
        AssignedTo: nobody puremagic.com

This program prints "-0" and then the assert fires, dmd 2.052:


import std.stdio, std.bigint;
void main() {
    writeln(BigInt(1)-1);
    assert((BigInt(1)-1) == 0);
}


Output:
-0
