[Issue]: flang-new: select case statement inside OpenMP target teams region

[VeeEM]

Problem Description

Compiler crashes/violates assertion if select case is used inside a target teams or target teams distribute parallel directive.

Operating System

SUSE Linux Enterprise Server 15 SP5 (Cray OS on LUMI)

CPU

AMD EPYC 7742 64-Core

GPU

AMD Instinct MI250X

ROCm Version

ROCm 6.2.2

ROCm Component

flang

Steps to Reproduce

target teams

$ cat teams.F90 
program teams
implicit none
integer :: i
!$omp target teams
select case (i)
case(1)
end select
!$omp end target teams
end program

$ flang-new -fopenmp teams.F90
