in thread substr outside of string? (Updated: Fixed in later builds.)

$a x= 2**31; creates an empty string,

Look again:

C:\test>perl $a = chr(0); $a x= 2**31; print length $a; substr( $a, 0, 2**16 ) =~ tr[\0][\1]; substr( $a, 2**16, 2**16 ) =~ tr[\0][\1]; ^Z substr outside of string at - line 3. 2147483648
