--- Comment #11 from Seth Johnson <johnsonsr at ornl dot gov> ---
I confirm that with both 10.2 and 8.3, the example code prints the erroneous
warning with `-O0` and works as expected (no warning) with `-O1` and higher.
```
$FC "-Wall" -O1 -c ./ftest.f90
```
```fortran
subroutine do_stuff()
character(len=*), parameter :: src = "nope"
character(len=:), allocatable :: dst
dst = src
write(*,*) dst
end subroutine
```
