static initialization order fiasco when init log object in static field

[pippocao]

memory_map_handle memory_map::create_memory_map(const bq::file_handle& map_file, const size_t offset, const size_t size)
{
memory_map_handle result;
if (!map_file.is_valid()) {
result.error_code_ = EBADF;
bq::util::log_device_console_plain_text(log_level::error, "create_memory_map with invalid map_file");
return result;
}
auto fd = map_file.platform_handle();
auto current_size = lseek(fd, 0, SEEK_END);
// alignment
size_t alignment_offset = offset % __memory_map_size_unit;
......
}

__memory_map_size_unit is defined as global static variable, which leads to static initialization order fiasco
