There have been significant changes since this ticket was filed.  I just tried this case in blead with valgrind and got no problems.  This is the output

Useless use of anonymous hash ({}) in void context at -e line 1.
Bareword found where operator expected at -e line 1, near "0ÿ"
        (Missing operator before ÿ?)
Constant(0): $^H{integer} is not defined at -e line 1, at end of line
