…tal, opt-in) options.enable_native_crash_handler (default off): installs handlers for SIGSEGV/ABRT/BUS/ILL/FPE/TRAP with SA_SIGINFO|SA_ONSTACK on a pre-allocated sigaltstack. The handler is write()-only over a pre-opened fd against a pre-captured module table (dl_iterate_phdr + NT_GNU_BUILD_ID) — no malloc, no locks — capturing PC (+LR on ARM) as (module, build-id, offset) frames, then chaining to any pre-existing handler (Unity/UGS) and re-raising the default so the process dies with the true signal. Dump is picked up at the NEXT launch and reported through the existing pipeline with crashType + osSignal; a native dump supersedes the generic unclean-shutdown, a restored managed crash still wins. Linux/Android only (fail-soft no-op elsewhere). Tests: pure parser (truncation-tolerant), take-once semantics, payload wire fields, and a Linux fork/SIGSEGV integration test asserting dump-written + chained-handler-ran + died-with-signal. v0.9.0.
…ts actually run The suite compiled but was absent from the add_test foreach list, so CTest never executed it (incl. the Linux fork/SIGSEGV chaining integration test).

In-process async-signal-safe native crash handler (Linux/Android), default-off via
options.enable_native_crash_handler. Dump-at-crash -> report-at-next-launch with (module,build-id,offset) frames, handler chaining, crashType/osSignal. See CHANGELOG 0.9.0. CI is the build gate (no local C++ toolchain); the Linux job runs a real fork/SIGSEGV chaining integration test.
