I'd say it's a wrong-code bug.

-------------------------------------
import std.math, std.stdio;
void main() {
      auto a = 1.0, b = 0.0;
      writeln(a);
      writeln(ieeeFlags.divByZero);
      auto c = a / b;    // <-- this is no longer dead right?
      writeln(c);
      writeln(ieeeFlags.divByZero);
}
