Since there is nothing wrong with the way you allocate and free, there must be something wrong with the way you use the allocated memory.

A common mistake is something like this

Code:

n = strlen(string);
char *p = malloc( n );  // BUG - should be n+1
strcpy( p, string );

Memory is corrupted because you copy one more byte than there is allocated space (therefore running into something else - usually some malloc/free control structure).
