    I tried manually removing -fomit-frame-pointer from Makefile and adding
    -fno-omit-frame-pointer but with same results - junk return addresses.
    Probably a X86_64 issue.

    >So it's probably an ndiswrapper bug?
    I looked at ndiswrapper mailing lists and found this explanation for the same
    issue of growing size-64 with ndiswrapper -
    ----------------------------------
    "It looks like the problem is kernel-version related, not ndiswrapper.
    ndiswrapper just uses some API that starts the memory leak but the
    problem is indeed in the kernel itself. versions from 2.6.10 up to
    .11-rc3 have this problem afaik. haven"t tested rc4 but maybe this one
    doesn"t have the problem anymore, we will see"
    ----------------------------------

    I tested -rc4 and it has the problem too. More over, with plain old 8139too
    driver, the slab still continues to grow albeit slowly. So there is a reason
    to suspect kernel leak as well. I will try binary searching...
