  C Compile options needed: none

        integer i

        print *, i             ! prints 0 (should print 1)

        read("7", *) i
        print *, i             ! prints 0 (should print 7)

        read(string, '(i1)') i ! work-around, perform a formated READ
        print *, i             ! prints 1

        read("17", *) i
