Using Mix_LoadMUS_RW causes crash

Source code from
https://lazyfoo.net/tutorials/SDL/21_sound_effects_and_music/index.php
I want to change
gMusic = Mix_LoadMUS("../test/asset/bgm1.wav");
to
std::vector<unsigned char> data;
if (!readFileToMemory("../test/asset/bgm1.wav", data))
{
printf("readFileToMemory error\n");
}
SDL_RWops *rwops = SDL_RWFromConstMem(data.data(), static_cast<int>(data.size()));
// gMusic = Mix_LoadMUSType_RW(rwops, Mix_MusicType::MUS_WAV, 1);
gMusic = Mix_LoadMUS_RW(rwops,1);
This will cause it to crash.
code for readFileToMemory:
bool readFileToMemory(const std::string &filePath, std::vector<unsigned char> &data)
{
std::ifstream file(filePath, std::ios::binary | std::ios::ate);
if (!file.is_open())
{
std::cerr << "Failed to open file: " << filePath << std::endl;
return false;
}
std::streampos fileSize = file.tellg();
if (fileSize <= 0)
{
std::cerr << "File is empty: " << filePath << std::endl;
file.close();
return false;
}
data.resize(static_cast<size_t>(fileSize));
file.seekg(0, std::ios::beg);
file.read(reinterpret_cast<char *>(data.data()), fileSize);
file.close();
return true;
}
version:
SDL2-2.28.0
SDL2_mixer-2.6.3
