# AddressSanitizer Build Script for OpENer
#
# This script builds OpENer with AddressSanitizer and UndefinedBehaviorSanitizer
# enabled for comprehensive security vulnerability detection.
#
# Usage:
#   ./build_with_sanitizers.sh [asan|ubsan|both]
#
# Environment Variables:
#   ASAN_OPTIONS: Configure AddressSanitizer behavior
#   UBSAN_OPTIONS: Configure UndefinedBehaviorSanitizer behavior
#
# Examples:
#   ./build_with_sanitizers.sh asan     # Only AddressSanitizer
#   ./build_with_sanitizers.sh ubsan    # Only UndefinedBehaviorSanitizer
#   ./build_with_sanitizers.sh both     # Both sanitizers
