I don't know, if there's a linker output for it... (now I'm gonna get
flamed...:-))... but ....

I did a little app a while back, where I totally removed the C runtime
from the final executable. (The purpose was to get a tiny tiny Win32
app). Without linking to the C runtime, I had to implement all runtime
functions used myself or let the compiler generate intrinsic
functions. Somehow there was one function missing in DEBUG or RELEASE
builds (don't remember which one it was, but I guess it was DEBUG):
_chkesp()

I looked at the assembly source and as far as I know this function was
called on almost every function leave. I think it's used to verify
that a function didn't mess with the stackframe...

Below is my implementation to get the linker happy, but I think you
might blow this function up a bit and monitor the ESP/EBP contents a
get some idea on stack usage from that...

Just a thought

SmallIO.cpp:
.....
extern "C" {
__declspec(naked) void __cdecl _chkesp(void)
{
    _asm
    {
        ret 0;
    }
}
};
.....
