Using std::format when importing <iostream> and <format> at the same time caused a SIGSEGV fault

Question

I used g++ -fmodules-ts -std=c++23 to compile a formatted "Hello Module!" but got SIGSEGV fault by calling std::format. If I didn't import <iostream> and then replace std::cout << format; with printf(format.data()); everything works well.

import <iostream>;
import <format>;

int main()
{
    std::string format = std::format("Hello {}!\n", "Module");
    std::cout << format;
    return 0;
}

GDB backtrace:

Thread 1 received signal SIGSEGV, Segmentation fault.

__nargs being UINT64_MAX seems to be weird.

I wonder if it's a bug of module feature, or, how to fixed this.
