Failed Parse on Character Array with multiple sub-index (FORTRAN)

Hello! I'm facing an issue with a specific program that access string sub-literals (Sorry if this is a known issue, or not supported, feel free to delete this if this is the case)

The offending code sample is:

```
program main

implicit none

integer :: k

character*80 c(80)

do k = 1, 15

c(k)(1:k) = 'FAILED PARSE'

end do

end program main
```

Full error log is:

```

Hope it helps!
