Crash itself is reproducible on godbolt. The reproducer here is reduced from https://github.com/gcc-mirror/gcc/blob/master/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90.
See https://godbolt.org/z/cxzK8Y3vs
```f90
program main
implicit none (type, external)
character(len=:), allocatable :: my_str
my_str = "1234567890"
call foo_str(my_str)
deallocate (my_str)
contains
subroutine foo_str(str)
integer :: i
character(len=*) :: str
!$acc parallel copyout(str)
str = "abcdefghij"
!$acc end parallel
end
end
```
With assertion-enabled flang, the reproducer hits the following assertion:
```txt
/path_to_project/llvm-project/flang/lib/Lower/OpenACC.cpp:164: Op createDataEntryOp(fir::FirOpBuilder &, mlir::Location, mlir::Value, std::stringstream &, mlir::SmallVector<mlir::Value>, bool, bool, mlir::acc::DataClause, mlir::Type, llvm::ArrayRef<mlir::Value>, llvm::ArrayRef<mlir::Attribute>, llvm::ArrayRef<mlir::Attribute>, bool, mlir::Value) [Op = mlir::acc::CreateOp]: Assertion `mlir::isa<mlir::acc::PointerLikeType>(baseAddr.getType()) && "expected pointer-like"' failed.
