malloc() memory corruption (C++)

Hello everyone,
I am kinda new to linux so... I need your help...

I have been programming a small programm, in C++... I tested my programm on Fedora, and everything went well... now I am trying to make it run on Ubuntu, but I keep having this error when compiling:

*** glibc detected *** malloc(): memory corruption: 0x08064eb0 ***

does anyone know what could cause it? thank you in advance

You might be freeing something which is already freed or one of the other usual suspects when doing C memory management.

If it's a C++ program, consider using new/delete instead of malloc/free, and do not mix them up!

The glibc error message you got isn't very helpful on it's own. valgrind might be able to help you pin down your error. If you fix it, don't forget to post here with some details and how you found the bug!
