           Summary: snn linked programs never release memory back to the
                    OS
           Product: D
           Version: 1.046
          Platform: All
        OS/Version: Windows
            Status: NEW
          Severity: blocker
          Priority: P1
         Component: Phobos
        AssignedTo: nobody@puremagic.com
        ReportedBy: dominik@vga.hr


Programs using GC or manual malloc/free never actually release memory back to the OS (Windows), which causes programs with heavy memory allocation / deallocation to utilize page swaps heavily and eventually crash.

This is a blocking issue persistent in 1.047 release also (it was not available in version selection).

You can trivially reproduce this effect by malloc'ing several MB's and subsequently freeing them - watch the process memory usage before and after it.

Actually, the garbage collector doesn't use malloc to allocate heap memory (it uses the OS-specific page allocation functions), but it does suffer from the same problem.
