Clang-compiled program crashes with segfault when fsanitize=address is on

Question

I created the minimal example C++ program and wanted to try out clang's address sanitizer:

#include <iostream>

int main()
{
    std::cout << "Hello World!" << std::endl;

    return 0;
}

I compile with below it works fine.

c++ -g -O1 -fno-omit-frame-pointer main.cpp -o main

When I compile with the sanitize flag on, I get a segmentation fault.

c++ -g -O1 -fno-omit-frame-pointer -fsanitize=address main.cpp -o main

My clang version is:

Ubuntu clang version 14.0.0-1ubuntu1.1
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

I am using libstdc++11 (the GCC standard library implementation): version GLIBCXX_3.4.30 and GLIBC_2.4

I also have the strace here:

... // before this line, there are many other similar lines that document finding the other .so libraries (like the libstdc++ for example)

I am pretty new to this, and not sure where to start looking. If any of you more experienced can advise me where to start digging, I would be grateful.
