[Issue 7810] [CTFE] Typesafe variadic function with array of structs
http://d.puremagic.com/issues/show_bug.cgi?id=7810
--- Comment #9 from Don clugd...@yahoo.com.au 2012-10-01 06:17:47 PDT ---
Further reduced shows it's a problem with void initialized static arrays. I
have a fix.
int bug7810() {
int[1][3] x = void;
x[0] = [2];
x[1] = [7];
assert(x[0][0] == 2);
return 1;
}
static assert(bug7810());

When compiling the following example module, DMD 1.075 or 2.060 crashes with
Segmentation Fault with -version=Crash; it does not without.
---
module crash;
class C
{
class D { }
}
void main ( )
{
auto c = new C;
version(Crash) auto d = c.new class C.D { };
}

[Issue 8743] Add support for memoizing class methods
http://d.puremagic.com/issues/show_bug.cgi?id=8743 --- Comment #1 from Andrej Mitrovic andrej.mitrov...@gmail.com 2012-10-01 13:19:45 PDT --- Here's another one that has rehashing ability: http://dpaste.dzfl.pl/abb6086f But it comes with a runtime cost of a boolean check. I'd love to be able to make rehash a compile-time parameter, but I can't seem to make opCall work with it. Even if it did work I'd have to figure out a way to store the hash outside of the template since each template instance has it's own internal hash. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

void rehash() { memo = null; }
Maybe do you mean something like this?
void rehash() { memo.rehash; }
void clear() { memo = null; }

[Issue 8745] New: floating point comparison (is vs ==) inconsistency (on 32)
http://d.puremagic.com/issues/show_bug.cgi?id=8745
Summary: floating point comparison (is vs ==) inconsistency
(on 32)

From http://forum.dlang.org/group/digitalmars.D.learn
//
import std.stdio;
import std.math;
@property double getFloat()
{
return sqrt(1.1);
}
void main()
{
writeln(getFloat() == getFloat());
writeln(getFloat() is getFloat());
}
//
x32 Produces http://dpaste.dzfl.pl/e0e0bbae :
false
true
x64 Produces http://dpaste.dzfl.pl/c1c7a415 :
true
true
While one may argue that the comparison *may* return false, the difference in
behavior between == and is not expected behavior (unless I'm missing
something...? ).
PS: the behavior difference is consistent http://dpaste.dzfl.pl/2ee9ae4e :
//
import std.stdio;
import std.math;
@property double getFloat()
{
return sqrt(1.1);
}
void main()
{
writeln(getFloat() == getFloat());
writeln(getFloat() is getFloat());
writeln(getFloat() is getFloat());
writeln(getFloat() == getFloat());
writeln(getFloat() is getFloat());
writeln(getFloat() == getFloat());
writeln(getFloat() == getFloat());
writeln(getFloat() is getFloat());
}
//
false
true
true
false
true
false
false
true
//
On a side note, I find it strange that == return false in such a consistent
manner. It might be over-sensitive to extended precision?

[Issue 4571] Non-null class references/pointers
http://d.puremagic.com/issues/show_bug.cgi?id=4571
--- Comment #6 from bearophile_h...@eml.cc 2012-10-01 14:26:20 PDT ---
A small program that shows three important things std.typecons.Nullable isn't
able to do:
import std.stdio, std.algorithm, std.typecons;
alias Nullable!(int, -1) Position;
void foo(int[] a, Position pos) /*nothrow*/ { // allow this to be nothrow
if (pos.isNull) {
return;
} else {
a[pos] = 10; // perform no nullness test here, optimization
}
}
void bar(int[] a, Position pos) {
a[pos] = 10; // compile-time error here?
}
void main() {
auto data = [1, 2, 3, 4, 5];
auto p = Position(countUntil(data, 7));
foo(data, p);
writeln(data);
}
