    Hi All,

    What would be the proper way to protect against this bug check? I've got a
    pointer that used to point into PCI space, but under certain conditions, the
    memory can currently be unmapped before the thread using that pointer knows
    about it. Clearly, I shall remove the cause of this problem as well, but it
    seems like a good idea to perform some checking before the pointer is used.
    I thought __try and __except might do it for me, but it doesn't seem to.

    Thanks in advance for any help,

    Ok, thanks. FYI I've now resolved the particular bug that was causing it in
    this case.
