Should give with -fbounds-check something like the following (NAG f95 -C=all):
Rank 1 of array operand has extent 8 instead of 4
Program terminated by fatal error
In BOUNDSERROR, line 7 of test.f90
I think it might a duplicate of some PR, though I couldn't find it.
program boundsError
implicit none
integer :: i
integer, dimension(:), allocatable :: y
allocate(y(4))
y = 0.0
print *, size(y)
y = [y, (99,i=1,4)]
print *, size(y)
end program boundsError

I forgot to mention: I think this file is valid Fortran 2003 and only invalid
Fortran 95. Maybe using:
integer, dimension(4) :: y
is a better test case.

It is caught at compile time:
y = [y, (99,i=1,4)]
1
Error: Different shape for array assignment at (1) on dimension 1 (4 and 8)

Not if you write it as:
n = 4
y = [y, (99,i=1,n)]
