WarpExecuteOnLane0Op::verify() called getTerminator() which performed an unconditional cast<gpu::YieldOp> on the block's last operation. When the op body was written with a different terminator (e.g. affine.yield), the cast asserted immediately instead of emitting a verifier diagnostic. Fix by using dyn_cast in verify() before calling getTerminator(), and emitting a proper error message when the terminator is not gpu.yield. Add a regression test to invalid.mlir. Fixes #181450
