I have written an application that is leaking memory – I’ve done the following in the past

  1. find the heap that’s leaking with
    !heap -s

  2. inspect the heap with
    !heap -stat -h

  3. see the callstack for the allocation with
    !heap -p -a

to get the callstacks I add +ust to gflags

while I’ve done this in the past with great success, !heap -s isnt showing any growth today? I have no idea whats wrong?

it’s like my allocations are in a heap hidden from !heap -s?

ideas? I’m compiling (both x86 and x64) using Visual Studio 2010 pro. Using windbg to debug

    the punchline – when allocations are <1MB (default) they go to HeapAlloc(), when they’re bigger than 1MB they go to VirtualAlloc instead

    VirtualAlloc doesnt appear with !heap -s
