      # Build the C/Cython extensions with AddressSanitizer and UndefinedBehaviorSanitizer enabled.
      # How this works:
      # - The -fsanitize=address,undefined flags inject runtime checks into our native code. If a bug is hit
      #   (e.g., buffer overflow, use-after-free, out-of-bounds, or undefined behavior), the sanitizer prints
      #   a detailed error report to stderr, including a stack trace, and forces the process to exit with
      #   non-zero status. In CI, this will fail the step/job so you will notice.
      # - ASAN_OPTIONS/UBSAN_OPTIONS configure the sanitizers' runtime behavior (see below for meanings).
      env:
        CFLAGS: "-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined"
        CXXFLAGS: "-O1 -g -fno-omit-frame-pointer -fsanitize=address,undefined"
        LDFLAGS: "-fsanitize=address,undefined"
        # ASAN_OPTIONS controls AddressSanitizer runtime tweaks:
        # - detect_leaks=0: Disable LeakSanitizer to avoid false positives with CPython/pymalloc in short-lived tests.
        # - strict_string_checks=1: Make invalid string operations (e.g., over-reads) more likely to be detected.
        # - check_initialization_order=1: Catch uses that depend on static initialization order (C++).
        # - detect_stack_use_after_return=1: Detect stack-use-after-return via stack poisoning (may increase overhead).
        ASAN_OPTIONS: "detect_leaks=0:strict_string_checks=1:check_initialization_order=1:detect_stack_use_after_return=1"
        # UBSAN_OPTIONS controls UndefinedBehaviorSanitizer runtime:
        # - print_stacktrace=1: Include a stack trace for UB reports to ease debugging.
        #   Note: UBSan is recoverable by default (process may continue after reporting). If you want CI to
        #   abort immediately and fail on the first UB, add `halt_on_error=1` (e.g., UBSAN_OPTIONS="print_stacktrace=1:halt_on_error=1").
