Why is the fourth line different, and where is it documented that it should be different?
'&' can be interpreted as the bitwise and operator, and in your 4th line it is. The file handle $fh is being bitwise anded with the result of the function call to hexdump(). Either omit the & (you don't need it anyway), or put parenthesis around the function call to disambiguate:
print $fh (& hexdump ());
