Summary: [64-bit] new bool returns bogus address
Product: D
Version: D2
Platform: x86_64
OS/Version: Windows
Status: NEW
Severity: normal
Priority: P2
Component: DMD
AssignedTo: nobody puremagic.com
ReportedBy: dsimcha yahoo.com
import std.stdio;
void main() {
auto b = new bool;
stderr.writeln(b);
*b = false;
}
The address I receive can't be right because it's in "no-man's land" part of
x64 address space, at least according to http://en.wikipedia.org/wiki/X86-64 .
At any rate, it segfaults the program.

Looking into it further, this seems to happen with any primitive type, for
example, "new double", "new uint". Amazingly, though, this code works:
import std.stdio;
void main() {
auto b = (new bool[1]).ptr;
stderr.writeln(b);
*b = 1;
}
