> I: Program causes undefined operation
>    (likely same variable used twiceand post/pre incremented in the same expression).
>    e.g. x = x++; Split it in two operations.

> I: Statement might be overflowing a buffer in strncat. Common mistake:
>    BAD: strncat(buffer,charptr,sizeof(buffer)) is wrong, it takes the left over size as 3rd argument
>    GOOD: strncat(buffer,charptr,sizeof(buffer)-strlen(buffer)-1)
