Same is true for any other intrinsic data type.
Test case for integer array:
program test
implicit none
integer, allocatable :: i(:)
i = [1]
end program
Compilation and warning:
$ gfortran -Wall -g3 -fcheck=all -fuse-ld=bfd a.f90
4 | i = [1]
|
Warning: ‘i.offset’ may be used uninitialized in this function
[-Wmaybe-uninitialized]
a.f90:4:0: Warning: ‘i.dim[0].lbound’ may be used uninitialized in this
function [-Wmaybe-uninitialized]
