❌ 5 New Failures, 3 Unrelated Failures

As of commit c7b0d35 with merge base c655dc6 ():

NEW FAILURES - The following jobs have failed:

• pull / test-llama-runner-qnn-linux (fp32, qnn_16a16w, qnn) / linux-job (gh)
  /pytorch/executorch/examples/qualcomm/oss_scripts/llama/qnn_multimodal_runner.cpp:272:32: error: variable type 'example::MultimodalRunner<unsigned short>' is an abstract class

• pull / test-sqnr-static-llm-qnn-linux (smollm2_135m) / linux-job (gh)
  /pytorch/executorch/examples/qualcomm/oss_scripts/llama/qnn_llama_runner.cpp:217:22: error: variable type 'example::Runner<unsigned short>' is an abstract class

FLAKY - The following jobs failed but were likely due to flakiness present on trunk:

• pull / test-quantized-aot-lib-linux / linux-job (gh) (detected as infra flaky with no log or failing log classifier)
• pull / test-static-llama-qnn-linux (stories_110m) / linux-job (gh) (matched linux rule in flaky-rules.json)
  The runner has received a shutdown signal. This can happen when the runner service is stopped, or a manually started runner is canceled.
• pull / unittest-arm-backend-with-no-deps (test_pytest_models_tosa) / linux-job (gh) (detected as infra flaky with no log or failing log classifier)
