For variable size strings, flang generates an artificial variable in the debug info that holds the length. While reviewing https://github.com/llvm/llvm-project/pull/134967, I noticed that variable inside the target region are using the artificial variable in the host for the length which is not working. As a result, the evaluation fails. The problem could be reproduced with the following program but it will need the changes in #134967 to compile.
```
module test
implicit none
contains
subroutine TestOfCharacter(a0, a1, l)
character(len=*), intent(in) :: a0
character(len=*), intent(inout):: a1
integer, intent(in) :: l
!$omp target map(to:a0) map(from: a1)
a1 = a0
!$omp end target
end subroutine TestOfCharacter
end module test
program main
use test
character(len=15) :: first
character(len=:), allocatable :: second
first = 'Short string'
second='This is a large string.'
call TestOfCharacter(first, second, 23)
print *, first
print *, second
end program
```
