Assume that one has the following code:
```Fortran
subroutine f_c_character(rhs, lhs, len)
character(kind=c_char), intent(out) :: lhs(*)
character(len=*), intent(in) :: rhs
integer, intent(in) :: len
integer :: length
length = min(len-1, len_trim(rhs))
lhs(1:length+1) = transfer(rhs(1:length), lhs(1:length)) // c_null_char
end subroutine f_c_character
```
Here is an assignment between two strings with possible truncation if rhs has larger length than lhs.
However, flang runtime says that the `Assign: mismatching element counts in array assignment`
Here is an example with current master where the error occurs:

gfortran + ASan does not give any errors (except leaking).
