The attached (er. Can't seem to attach the file, I'll e-mail it to anyone
who's willing to take a look) has a bug on WinXP DMD 1.040. I can't seem
to reduce it at all as anything but trivial changes (like removing dead code)
seems to make the bug vanish.
The short description is I have some code that looks something like this:
bool Foo()
{
bool ret = true;
writef(ret,'\n');
return ret;
}
unittest
{
auto ret = Foo();
writef(ret,'\n');
assert(ret);
}
output:
true
false
Assert Failed

Reply to Kagamin,BCS Wrote:Yes that's the spot that was (is?) generating an error. I'm not so sure anymore as my system is no longer reproing but I seem to recall that it was printing out true inside the opEquals function but false outside. BTW the first function in that file had a bug and should be: //Usable AlmostEqual function bool ULP(T)(T A, T B, uint maxUlps) { if(A == B) return true; static if(is(T == float)) { alias int Tint; Tint bound = 0x8000_0000; } else static if(is(T == double)) { alias long Tint; Tint bound = 0x8000_0000_0000_0000; } else static assert(false, "only float or double can be used, not "~T.stringof); // Make sure maxUlps is non-negative and small enough that the // default NAN won't compare as equal to anything. assert(maxUlps > 0 && maxUlps < 4 * 1024 * 1024); auto aInt = *cast(Tint*)&A; // Make aInt lexicographically ordered as a twos-complement int if (aInt < 0) aInt = bound - aInt; // Make bInt lexicographically ordered as a twos-complement int auto bInt = *cast(Tint*)&B; if (bInt < 0) bInt = bound - bInt; auto ulp = abs(aInt - bInt); if (ulp <= maxUlps) return true; return false; }I've posted the code here: http://smplsite.com/filebox/error.zipauto r = (rp == Point(-.5,1.5)); writef("---%s\n", r); assert(r, "++"~rp.toString); Is this it?

Reply to Nick,Ok, WinXP 32-bit, and on both 1.040 and 1.041 (byte-for-byte identical output on both), my output from go.bat was:...Hmm. IIRC my home box gave:---truetrue--- false but I just ran it on my work boxes and got:true--- false I'll have to recheck the home machine. With a bit more digging it seems that right now I'm getting an almost equal error that writef was hiding by rounding. I've already got a fuzzy equal so I guess I just need to do some tuning.false
