I see

[macbook] f90/bug% gfc -Warray-temporaries pr45159_4_red.f90
pr45159_4_red.f90:7.15:

  a(-3:9:3) =  a(-6:18:6)
               1
Warning: Creating array temporary at (1)

which is an instance of

l_start<r_start+r_stride for r_stride>max(0,l_stride)

(see comment #19) for which there is no dependency.
