gdb pretty-printers: fix StringPrinterHelper for gdb 8.0
Latest gdb release "lazy_string" validates the array size: Traceback (most recent call last): File "/work/lo/master/solenv/gdb/libreoffice/util/string.py", line 29, in to_string return self.make_string(data, self.encoding, len) File "/work/lo/master/solenv/gdb/libreoffice/util/string.py", line 66, in make_string return data.lazy_string(encoding, length) gdb.error: Length is larger than array size. rtl_uString has "sal_Unicode buffer[1];", which is a lie as the real size is the same as "length". Taking the address of "buffer" appears to avoid the exception. Change-Id: I85710b1adfae584ba09c8d517e9b49b290e79d8a
