Sanitizer Reproduction

Use this skill for security advisories, crash reports, fuzzing artifacts, or manual findings involving iccDEV command-line tools.

Workflow

Build from a clean CMake cache with sanitizer flags.
Verify sanitizer linkage before claiming coverage.
Run the exact reproduction command and capture exit code plus stderr.
Classify exit codes: 0 success, 1-127 graceful failure, 128+ signal.
Attribute root cause from sanitizer stack frames, not PoC filenames.
Inspect tool argument semantics before writing a one-liner. If a tool appends channel numbers, expands prefixes, or parses config files, preserve that behavior in the command instead of copying artifacts to synthetic names.
Minimize reproduction steps while keeping them copy-pasteable. When a maintainer asks for no substitutions, the command must start with the tool binary and use literal arguments only; do not use shell variables, loops, mktemp, or copy helpers.
File or update issues using the canonical security format.

Build

cd Build && rm -rf CMakeCache.txt CMakeFiles/
CC=clang CXX=clang++ cmake Cmake -DCMAKE_BUILD_TYPE=Debug -DENABLE_TOOLS=ON -DENABLE_ASAN=ON -DENABLE_UBSAN=ON -DENABLE_INTEGER_SANITIZER=ON -DENABLE_FLOAT_SANITIZER=ON
make -j"$(nproc)"
nm Tools/IccDumpProfile/iccDumpProfile | grep -c __asan

Use CC=clang, not C=clang; after any failed compiler configure, delete both CMakeCache.txt and CMakeFiles/ before retrying. Do not enable coverage for a sanitizer reproduction because coverage instrumentation can mask findings.
