- Add optional libunwind support for better stack traces on ARM (glibc's backtrace() doesn't work well on ARM due to missing frame pointers) - Fix misleading signal info: si_pid/si_uid/si_status are only valid for SIGCHLD, not for SIGSEGV/SIGBUS - they were showing garbage values (the fault address misinterpreted as PID) - Add human-readable fault descriptions for SIGSEGV, SIGBUS, SIGFPE, and SIGILL signals - Use clearer terminology in error messages To enable libunwind on ARM: apt install libunwind-dev Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
