*** glibc detected *** ./PROGRAM_NAME: free(): invalid pointer: ADDRESS ***

• produced with GCC 4.4.3?
• May also produce a "segmentation fault" error
• May cause program execution to break well before the true faulty area of code
• Check for function declarations and definitions that do not match
• Check for missing or invalid return types in function definitions

// function declaration below has no return type in its' definition
foo checkfoo(); 
// instead it should be
void checkfoo();
