Here you are:
--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----
(gdb) p PT_ADDR
$1 = (unsigned char *) 0x521073e " long as we don't have any longer the \\NEWLINE the problem is solved. So it could be:\n\n\n\n--8<----8<----8<----8<----8<-- begin -->8---->8---->8---->8---->8----\n in_input_funnies=`echo \"$in_input\" \\\n "...
(gdb) p GPT_ADDR
$2 = (unsigned char *) 0x5210677 ""
(gdb) p GPT
$3 = 1651
--8<----8<----8<----8<----8<-- end -->8---->8---->8---->8---->8----

sentence « So it could be: ... ».
VBR,
Vincent.
