**Describe the bug**
When running an AFQMC complex dataset on 1 GPU, I get a segfault during Propagator initialization:

**System:**
- NVIDIA DGX-1 (V100)
- containerized environment based on Ubuntu 22.04, llvm 16, openmpi 4.1.5, ucx 1.13.1, CUDA 11.8
- have not yet tried other systems

**Additional context**
I can provide a core.dump (54GB) if helpful, still figuring out if I can share the dataset that was provided to me from a customer.
