* c-valprint.c (c_value_print): When doing virtual base pointer
	adjustment, create a new value with adjusted contents rather than
	changing the contents of the value being printed (and getting it
	wrong).

	gdb/testsuite/
	* gdb.cp/virtbase.cc (VirtualBase, VirtualMiddleA, VirtualMiddleB)
	(Virtual): New structs.
	(virtual_o, virtual_middle_b): New globals.
	* gdb.cp/virtbase.exp: New tests.
