Short: Mungwall & Enforcer DB tool w/o MMU (bugfix)
Author: thor@einstein.math.tu-berlin.de
Uploader: thor@einstein.math.tu-berlin.de
Type: dev/debug
_____________________________________________________________________________
The memsniff release 1.09 was broken, please upgrade to 1.10.
I have to apologize for the broken 1.09 - it caused really a lot of crashes.
After a long debug session for over eight hours it turned out that this
problem was not caused by MemSniff, but by "MagicMenu" !
The details are a bit tricky, but if you're interested what was going
wrong, read the "bugreport" in this archive. Anyways, MemSniff works now
sucessfully with MM, even though I would say that this tool contains
(another) bug.
_____________________________________________________________________________
Purpose of this program:
This program finds illegal memory changes by continously checking the free
memory. It also protects the memory allocation functions in a mungwall like
way. An exteral terminal or a interal low-level-debugger (like COP from the
same author) is recommended, but not needed.
MemSniff is not a Enforcer-replacement cause you can't replace the full
functionality of a MMU, but it does everything possible to find memory
violations.
It does not:
-protect memory already allocated, since this is not possible without a MMU
Since this memory checking is a bit tricky, there ARE KNOWN incompatibilities.
DO NOT RUN MemSniff permanently, cause it slows down your system considerably
and reduces the size of the available memory up to the half!
Known incompatibilities:
-Does not work well with memory defraction utilities, like PoolMem from
the same author.
-Does not work well with the SaferPatches utility of the same author, unless
you install SaferPatches with a special option.
Greetings, happy debugging,
Thomas.
