# Reproduce `consan-tiny`

Sanitizer case `consan-tiny` from run `2026-09-04T124232-33872660689` of the AORTA sanitizer nightly. This directory is the run area for that one case: its report, the sanitizer output the verdict came from, and the provenance below. See `index.html` for every file actually published here.

## Run

- Commit: `4b4553ef14af08e7ee2d68a888b68cd6a88803f7`
- Date: 2026-09-04 12:42:32 UTC
- Target: `gfx950`
- Class: survey (observed-only, non-gating)
- Workflow run: https://github.com/ROCm/aorta/actions/runs/33872660689
- Container image: `rocm/pytorch:rocm10.0_ubuntu26.04_py3.14_pytorch_release_2.13.0@sha256:3174cb7061d94c427da96c0edef4adea28046fa3f3b2ff3948dc4e995665ff8c`
- rocjitsu bundle: `f92da4cb3c5b3612db3752a36f4f3d0d3e9ff768` (https://github.com/ROCm/rocm-systems/actions/runs/33641388794)

## Observed

- Verdict: `error`
- Execution: `error`
- Findings: 0
- Reason: `combined_hook_exit_86`

## Run it yourself

First, the checkout this run used:

```
git clone https://github.com/ROCm/aorta && cd aorta
git checkout 4b4553ef14af08e7ee2d68a888b68cd6a88803f7
pip install -e .
```

Then rebuild the CI-built fixtures, which are not published here (see 'Artifacts not published' below). Run these from the repo root, the directory the clone above leaves you in:

- fixtures/isa/tiny.hsaco -- a gfx code object built from fixtures/kernels/tiny_vecadd.hip: `export PATH="$(python -c "from aorta.instrumentation.rocm_paths import resolve_rocm_roots; print(resolve_rocm_roots().llvm_bin_dir)"):${PATH}"`; `export LD_LIBRARY_PATH="${LD_LIBRARY_PATH:+${LD_LIBRARY_PATH}:}$(python -c "import os; from aorta.instrumentation.rocm_paths import resolve_rocm_roots as r; x = r(); print(os.pathsep.join(dict.fromkeys([str(x.core_lib_dir), str(x.lib_dir)])))")"`; `mkdir -p recipes/sanitizers/fixtures/isa`; `hipcc --genco --offload-arch=gfx950 recipes/sanitizers/fixtures/kernels/tiny_vecadd.hip -o tmp.o`; `if head -c 24 tmp.o | grep -qF __CLANG_OFFLOAD_BUNDLE__; then clang-offload-bundler --type=o --unbundle --input=tmp.o --targets=hipv4-amdgcn-amd-amdhsa--gfx950 --output=recipes/sanitizers/fixtures/isa/tiny.hsaco; else cp tmp.o recipes/sanitizers/fixtures/isa/tiny.hsaco; fi && rm -f tmp.o`. The conditional matters: --genco emits a raw code object on some ROCm builds and a clang-offload bundle on others, and the recorded digest is of the unbundled object.
- fixtures/bin/consan_tiny_load -- a host repro binary built from fixtures/kernels/consan_load.hip: `export PATH="$(python -c "from aorta.instrumentation.rocm_paths import resolve_rocm_roots; print(resolve_rocm_roots().llvm_bin_dir)"):${PATH}"`; `export LD_LIBRARY_PATH="${LD_LIBRARY_PATH:+${LD_LIBRARY_PATH}:}$(python -c "import os; from aorta.instrumentation.rocm_paths import resolve_rocm_roots as r; x = r(); print(os.pathsep.join(dict.fromkeys([str(x.core_lib_dir), str(x.lib_dir)])))")"`; `mkdir -p recipes/sanitizers/fixtures/bin`; `hipcc --offload-arch=gfx950 -DOBJECT="\"$(pwd)/recipes/sanitizers/fixtures/isa/tiny.hsaco\"" recipes/sanitizers/fixtures/kernels/consan_load.hip -o recipes/sanitizers/fixtures/bin/consan_tiny_load`. The -DOBJECT define is required: it is how the binary learns which code object to load.

The exact invocations the nightly used are in .github/workflows/sanitizers-nightly.yml.

Set `ROCJITSU_PREBUILT` (unpacked rocjitsu bundle supplying rj_waitcheck and the ConSan hook) before running. `aorta` sets `HSA_TOOLS_LIB`, `HSA_TOOLS_DISABLE_REGISTER`, `RJ_CONSAN_MODE`, `RJ_CONSAN_POLICY` for you from the recipe's policy block.

Finally, the sweep itself:

```
aorta sweep run --recipe recipes/sanitizers/daily-consan-tiny.yaml
```

## Artifacts not published

These are CI-built and too large to publish for every retained run. Rebuild them as above and check the digest matches.
