Re: [Dev-C++] memory leak!

[Lloyd <ll...@cd...>]

Thank you Jonathan. I tried using valgrind, but my program uses
wxWidgets (a GUI library). The out put of valgrind is unreadable and not
understandable for me :(

It shows lots of lines as output

When I executed my program more and more, at the first stages (first few
100 files) of file mapping no leak is shown, but when I go further, for
each 10 or 15 files 1MB to 3MB of leak is shown! I am not understanding
whats happening. Is there any chance of going something in the OS? 

Thank you, 
  Lloyd
