| currently
I'm not sure if it would be even possible.
Unless... *brainstorm*
If you used C++ you could modify several operators and add them to your wrapper
Let's see: & and *, [] those allow you to get the dynamic references to memory.
At least that way you can know if YOUR code is corrupting the memory.
Unfortunately that way you can't catch it if it is being done in libc by invalid
parameters or something like that.
I don't know if it's feasible but... good luck anyway.

| In the case of writing a wrapper, what functions would I need to make a

| the
| malloc() function, so I can also test for occurances, that overwrite those
Let's see... vi, grep, sources of libc, sources of the kernel. I guess you have
everything to study how memory is managed in linux. My bet goes to the sources of libc
Grep for malloc and free.
