This is a well-known and long-standing property of valgrind. For instance: http://valgrind.10908.n7.nabble.com/valgrind-does-not-handle-long-double-td41633.html [Search the 'net for "valgrind long double".] There is no solution. If IEEE-754 'double' is not good enough for you, then valgrind is not good enough for you. ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
