- which file? on numba side or llvmlite side?
- Note: first we need to isolate the reason.
  - Is it a pattern that occurs after pruning + optimization, such that it requires a 2nd run of the pruner?
  - Is it a failure in llvmlite refpruner implementation? The impl is at: https://github.com/numba/llvmlite/blob/06fb732e846dd3b4d922562c0c1bd00a96c2e4c9/ffi/custom_passes.cpp#L161
