2 StableHLO IRs abort at hlo_instructions.cc:2415 fused_root->IsFusible() …. Both IRs are included in ir.zip, one folder per IR; each folder contains the IR itself and a README with the environment, the crashing command and its output, the reference command that runs successfully, and the per-backend outcome for that IR.
