substr outside of string
(W substr),(F) You tried to reference a substr() that pointed outside of a string. That is, the absolute value of the offset was larger than the length of the string. See . This warning is fatal if substr is used in an lvalue context (as the left hand side of an assignment or as a subroutine argument for example).
