[Issue 5996] [CTFE] Undefined function call in auto return function

Reduced test case:
My second example shows an error message with missing line number:
Error: array index 4294967295 is out of bounds [][0 .. 0]
I have reduced it to this, I think it's better to fix this before fixing your
reduced test case:
auto foo(int n) {
auto h = new typeof(something)[n];
return h[$];
}
enum uint f = foo(1);
void main() {}

With DMD 2.053 the second assert of this program fires, is this a DMD bug?
struct Foo {
int[] data;
this(int n) {
data.length = n;
}
this(this) {
data = data.dup;
}
}
void main() {
Foo f1, f2;
f1 = Foo(1);
f2 = f1;
assert(f1.data.ptr != f2.data.ptr); // OK
f1 = f2 = Foo(1);
assert(f1.data.ptr != f2.data.ptr); // asserts
}

It's a problem with the gagging system. It actually shouldn't get as far as
CTFE, so the out-of-bounds error shouldn't happen.

Instead it should throw ConvException.
Some code and versions:
import std.conv;
void main() {
to!real(-);

[Issue 5667] [GSoC] clear does not call destructors on structs embedded in structs

I think I found a fix, but I'm not sure if it's correct as I don't know much
about the D runtime. In file object_.d, line 2600:
void clear(T)(ref T obj) if (is(T == struct))
{
- static if (is(typeof(obj.__dtor(
- {
- obj.__dtor();
- }
+ typeid(T).destroy( obj );
auto buf = (cast(ubyte*) obj)[0 .. T.sizeof];
auto init = cast(ubyte[])typeid(T).init();
if(init.ptr is null) // null ptr means initialize to 0s
buf[] = 0;
else
buf[] = init[];
}
This fixes it for me. You need to modifiy import/object.di as well, because
object_.d doesn't get header'd into object.di, for some reason I don't know.
I might make a pull request, but I'm not 100% this is correct, I would like to
get some feedback.

Declaring the property setter first makes the code compile again, which seems wrong, as there should be no reason for the declaration order to matter. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email --- You are receiving this mail because: ---

Tested in DMD 2.053:
auto foo(lazy int x){return {return x;};}
auto bar(lazy int x){return foo(x);}
void main(){assert(foo(1)()==bar(1)());} // assertion failure
Workaround:
auto foo(lazy int x){return {return x;};}
auto bar(lazy int x){return foo({return x;}());} // destroy purpose of 'lazy'
void main(){assert(foo(1)()==bar(1)());} // pass
Some funny stuff:
import std.stdio;
void main(){
auto x=bar(1);
writeln(x());
}
writes:
Garbage integer value
0
Where does 0 come from?
void main(){
writeln(bar(1)());
}
writes:
Garbage integer value
Segmentation Fault

The code below will not compile:
import std.regex;
void main(){
auto re = regex(foo.dup);
}
src\phobos\std\regex.d(1537): Error: cannot cast a
read-only string literal to mutable in CTFE
src\phobos\std\regex.d(1537): Error: cannot evaluate
tuple(,\x01) at compile time
I think there is a bug report on this, but also notice the instantiation line
isn't given (only the line in regex.d).

Well it's not a bug in DMD. The issue is that CTFE got an upgrade, and detects
more subtle bugs it seems.
The main issue is that it no longer works with mutable patterns.
This also fails:
import std.regex;
void main(){
char[] a = new char[256];
auto re = regex(a);
}
So it's a bug in std.regex, at that exact line. (Again: it is an issue of
sloppy typecheck)
I'll see about a proper fix.
