http://d.puremagic.com/issues/show_bug.cgi?id=3284 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. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
