If one sets the breakpoint in _gfortrani_next_format, one gets for the
original, non cached version:

(gdb) p dtp->u.p.fmt.array.array[1].source
$13 = 0x7fffffffdec6 "1H ),6h===== ,a  12,i4,6h =====)", ...


For the second round, one gets:
(gdb) p dtp->u.p.fmt.array.array[1].source
$14 = 0x7fffffffdec6 ' ' <repeats 26 times>, "=====)      \f"

Thus, the "source" string is not carried over.
