Bug Summary

File:projects/compiler-rt/lib/lsan/../sanitizer_common/sanitizer_flags.h
Warning:line 27, column 8
Excessive padding in 'struct __sanitizer::CommonFlags' (50 padding bytes, where 2 is optimal). Optimal fields order: external_symbolizer_path, strip_path_prefix, log_path, clear_shadow_mmap_threshold, color, mmap_limit_mb, hard_rss_limit_mb, soft_rss_limit_mb, coverage_dir, stack_trace_format, sancov_path, malloc_context_size, verbosity, print_module_map, handle_segv, handle_sigbus, handle_abort, handle_sigill, handle_sigfpe, allocator_release_to_os_interval_ms, dedup_token_length, exitcode, symbolize, allow_addr2line, fast_unwind_on_check, fast_unwind_on_fatal, fast_unwind_on_malloc, handle_ioctl, log_exe_name, log_to_syslog, detect_leaks, leak_check_at_exit, allocator_may_return_null, print_summary, check_printf, allow_user_segv_handler, use_sigaltstack, detect_deadlocks, legacy_pthread_cond, intercept_tls_get_addr, help, heap_profile, can_use_proc_maps_statm, coverage, full_address_space, print_suppressions, disable_coredump, use_madv_dontdump, symbolize_inline_frames, symbolize_vs_style, no_huge_pages_for_shadow, strict_string_checks, intercept_strstr, intercept_strspn, intercept_strtok, intercept_strpbrk, intercept_strlen, intercept_strndup, intercept_strchr, intercept_memcmp, strict_memcmp, intercept_memmem, intercept_intrin, intercept_stat, intercept_send, decorate_proc_maps, abort_on_error, suppress_equal_pcs, print_cmdline, html_cov_report, dump_instruction_bytes, dump_registers, consider reordering the fields or adding explicit padding members
