The issue arises when building the Kokkos-OpenMPTarget backend of TestSNAP (a proxy app for SNAP in LAMMPS package).
App builds and runs fine in `Release` mode.
Compiler used - clang/16, clang/17.0.6
Architecture - A100
Steps to reproduce the issue.
Clone a release or develop branch of Kokkos from [here](https://github.com/kokkos/kokkos).
Build OpenMPTarget backend
```bash
cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Debug -DCMAKE_INSTALL_PREFIX=$kk_install_path -DKokkos_ENABLE_OPENMPTARGET=ON -DKokkos_ARCH_AMPERE80=ON -DKokkos_ENABLE_TESTS=OFF ../
```
Clone `Kokkos_V2` branch of TestSNAP from [here](https://github.com/FitSNAP/TestSNAP).
Use the following cmake command
```bash
cmake -DKokkos_ROOT=$kk_install_path -Dref_data=8 -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release ..
