Please see the following program
```
PROGRAM test
implicit none
integer i
type :: t1
integer :: i1
end type t1
type(t1), dimension(10) :: v2
call fn()
CONTAINS
subroutine fn()
!$omp target map(alloc: v2(:))
v2(5)%i1 = 5
!$omp end target
end subroutine
end program test
```
When compiled with
flang -fc1 -emit-llvm -debug-info-kind=standalone -fopenmp
it fails with the following error:
```
conflicting debug info for argument
#dbg_declare(ptr %1, !41, !DIExpression(), !40)
!39 = !DILocalVariable(name: "v2", arg: 2, scope: !35, file: !4, line: 22, type: !9)
!41 = !DILocalVariable(name: "v2", arg: 2, scope: !35, file: !4, line: 23, type: !9)
error: failed to create the LLVM module
```
The reason seems to be that variable v2 is mapped twice and get 2 DeclareOp (and 2 local variables) in the outlined function for target region. This eventually maps to same location and cause this verification failure.
