           Summary: cstream is completely unusable on x86_64
           Product: D
           Version: D2
          Platform: x86_64
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: lomereiter gmail.com



PDT ---
Even the simplest piece of code segfaults:

import std.cstream;

void main(string[] args) {
    auto _dout = new CFile(stdout, FileMode.Out);
    _dout.printf("%d", 123);
}


With GDC it doesn't even link.

In 32-bit chroot cstream seems to work as expected.

This is because printf in std.stream is 32bit-centric:

----
  size_t printf(const(char)[] format, ...) {
    va_list ap;
    ap = cast(va_list) &format;
    ap += format.sizeof;
    return vprintf(format, ap);
  }
----

on x86_64, this would pass vprintf garbage.

Regards
