Free memory has is managed by the heap data structure. If you free an address
twice or free an adress that was never allocated, the data structure will get
corrupted. Often this does occur silently, but in a later state a malloc or
free call with this corrupted data structure might crash your application.

I don't know your application and thus I am not even sure that this is the
source of your problem. This was just a wild guess as it is a typical error in
such situations.
