http://d.puremagic.com/issues/show_bug.cgi?id=5571 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.

http://d.puremagic.com/issues/show_bug.cgi?id=5571 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; } -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
