  "message": "Switch GitHub Actions to Ubuntu 26.04 and enable control-flow coverage.\n\nAlso fix compatibility issues exposed by newer GCC and Clang versions on Ubuntu 26.04:\n- Bump `abseil-cpp` to `20260817.0` (in `MODULE.bazel`, `MODULE.bazel.lock`, and `cmake/BuildDependencies.cmake`) to pick up the `\u003cbmi2intrin.h\u003e` -\u003e `\u003cimmintrin.h\u003e` fix in `raw_hash_set.h` needed when GCC 15 targets `x86-64-v3` (`__BMI2__`) by default.\n- Avoid `std::atomic\u003cbool\u003e` and `std::copy` in SanitizerCoverage tracing hooks (`ExecutionCoverage` and `TableOfRecentlyComparedBuffers::Insert`), using `__atomic_load_n`, `__atomic_store_n`, and `__builtin_memcpy` instead to prevent infinite recursion when unoptimized builds link instrumented COMDAT symbols with `_GLIBCXX_ASSERTIONS` enabled by default in `libstdc++` 15, and include `meta.h` directly in `table_of_recent_compares.h`.\n- Move `GetTypeName()` into `type_support_internal` so `PRETTY_FUNCTION` fits within GCC\u0027s 80-character `std::string_view` compile-time debug printing limit and preserves the `fuzztest::internal::` namespace prefix.\n- Avoid calling `std::memcpy` with a null `out.data()` pointer on empty byte vectors in `IRObject::ToCorpus`, preventing Clang from optimizing away the empty-vector branch via `memcpy`\u0027s `nonnull` attribute.\n\nPiperOrigin-RevId: 1004136793\n",
