Note that the cast doesn't help in itself (but for the warning) as Jakub
notices.
The deeper issue is type-based aliasing here. IMHO libgfortran would need to
use
struct A { float *base_addr; size_t

Further reduced test
REAL*8 :: a8(16),b8(4,4), c8(16), d8(4,4)
c8=RESHAPE(b8,(/16/))
d8=RESHAPE(a8,(/4,4/))
