Hi, I tried allocating and deallocating on the same heap i.e. the heap belonging to the DLL. However, the problem still persists. Looks like there might be some other problem.
I have uploaded the modified version of the programs as a tarball with a README file for installing and running the program should you decide to try it out yourself. Here is the url: http:://www.cs.ucsb.edu/~tsanyal/mem_leak_demo.tgz Would appreciate any more ideas.
