[Bug target/20608] Bus Error - union of structures

The code is invalid: you're dereferencing a t_m pointer through a cast to
pointer to t_u.  Now the structures don't have the same alignment (t_m is 32-bit
aligned while t_u is 64-bit aligned).  I guess this accidentally worked in 3.4.x
because u was overaligned on the stack.
