Debugging with ddd : crashes in rtl_ImplGetFastUTF8UnicodeLen

Found it where it crashes at line 645 in Connection.cxx
OUString aData(pResults + 3,
                           isc_vax_integer(pResults, 2),
                           RTL_TEXTENCODING_UTF8);
            
and here is the backtrace at line 634 in ustring.cxx
Program received signal SIGSEGV, Segmentation fault.
