without seeing your code, we can not really help you...

anyway, Devel::Size doesn't take into account memory consummed by non-perl structures.

Are you compiling the C module with debugging information, doing so can add a lot of "rubbish" to the library... though usually no so much!

Check that you are passing the right size to the perl memory functions and macros, their argument types and order are inusual and passing the wrong arguments is not so rare!
