sanitize-common

# Shared base for the sanitizer profiles. Each mode profile (sanitize-asan, sanitize-ubsan,
# sanitize) inherits this with include() and appends its own -fsanitize=... flags. Requires
# conan/settings_user.yml (installed by `make bootstrap-sanitize`) for the compiler.sanitizer
# subsetting, which gives instrumented dependency binaries a distinct package_id.

# Sanitizer runtime options use this profile as their single source of truth. Conan injects [runenv]
# into the generated conan-debug-<sanitizer> CMake test presets (and conanrun env scripts);
# the public sanitize* test presets in CMakePresets.json inherit those, so `ctest`/`cmake
# --workflow` runs the instrumented tests with these options. ASAN_OPTIONS is ignored by a
# UBSan-only build and UBSAN_OPTIONS by an ASan-only build, so both are safe for every mode.
