C ++，捕获错误作为引用时出现Segfault

Question

when I catch any exception as a reference and try to access it with e.what(), I get an Segfault. Does anyone have an idea, why this happens?

#include <stdexcept>
#include <iostream>

int main(){
    try{
        throw ::std::runtime_error("test");
    }catch(::std::exception const &e){
        ::std::cerr << e.what() << "\n";
    }
}

I get:

 bash: line 1: 22110 Segmentation fault      (core dumped) 'test' < /dev/null > 'test.stdout' 2> 'test.stderr'

With ASAN I get:

ASAN:SIGSEGV
