Problem with the DLLs memory allocation

Dear All

I have the very strange problem, I have one DLL build under vc.6 and another
Dll also bulid under vc.6

For beter understanding lets take the name of two dlls

Dll_one
Dll_two

Now Dll_two is build by myself, and I am running and testing this Dll, its
gving the desird and correct result.

Now DLL_One is not build by me, and its also working fine, and giving
the expected result.

Both the Dll require lets say (80000 Bytes as the Input), here I mean the
Input data is same for both the Dll (both has the diffrent algo)


If I write the test code for the Dll_one and run it works
If I write the test code for the DLL_two (Build by me) it also work fine.

Now As I have to integrate these two Dlls as they take same argument,
So i have to run one DLL first and then Run second DLl.

For this when I write the test code I was able to build it and compile it
But when I execute then I get the error code of my DLL Stating that
their is the memory allocation failure.

what is the problem ?? i am not geting it, for this as the specifically when
 I
run the DLL sperately then both of them are working, But when pur together M
y
Dll states that their is memory allocation failure.

Please suggest me how to fix it.


Any commnets will be Highly thankful.
If you all think i have given less information then feel free to ask me.

Thanks In Advance
