Seem ok (null_info_size is correct, row_size and num_cols seem valid,
columns and current_row are valid pointers)

(gdb) print i
$2 = 1
(gdb) print res_info->columns[0]
$3 = (TDSCOLINFO *) 0x2c206e75
(gdb) print res_info->columns[1]
$4 = (TDSCOLINFO *) 0x6c6c6162
(gdb)

??? garbage ??

(gdb) print *(res_info->columns[0])
Cannot access memory at address 0x2c206e75
(gdb) print *(res_info->columns[1])
Cannot access memory at address 0x6c6c6162
(gdb)

... garbage !!!
However I don't understand why i is 1 and not 0...
