This patch causes OpenMC offloaded via OpenMP on AMDGPUs to crash at runtime. It looks like some corruption in the memory address.
You can find build instructions here: https://github.com/jtramm/openmc_offloading_builder

The commit before this one works fine though, assuming you cherry picked https://reviews.llvm.org/rGee1d000d43321590771a2f047c8c55d07d09ad28 first as it landed after.
I assume other codes will be impacted too.
