C++ Exceptions and Static Linking

I'm trying to use exceptions in a C++ code that runs on raspberry-pi zero. When I link the code dynamically it works fine. However, when I link it statically, I get:

terminate called after throwing an instance of 'std::exception'
terminate called recursively
Aborted

An example code to reproduce the problem:

#include <exception>
#include <stdio.h>

void foo(void)  
{  
    throw std::exception();  
}  

int main (void)  
{  
    try  
    {  
        foo();  
    }  
    catch(...)  
    {  
        printf("caught an exception\n");  
    }  

    return (0);  
}

My "problematic" link command is: g++ exceptionTest.cpp -o exceptionTest.out --static

Why does the static linking disrupts the exceptions mechanism?
Is there something I could do in my link command (e.g. add flags) to fix this?

Note: my problem appears very similar to GCC arm-none-eabi (Codesourcery) and C++ Exceptions but the OP there worked on a different system and the suggested solution was related to a link script (which I don't use).

The exact same problem occurs in the raspberry-pi-2 and raspberry-pi-3 as well. – Tal Ben-Porath Sep 05 '19 at 08:48
Can you try adding `-fexceptions` ? – Richard Critten Sep 05 '19 at 08:57
I tried adding "-fexceptions" and the problem remained. – Tal Ben-Porath Sep 05 '19 at 09:06

Try passing `-static` instead of `--static`. The latter seems like a direct linker option, so the driver might not handle it completely correctly. (just an idea though, not sure if this makes any sense) – rubenvb Sep 05 '19 at 09:44
"-static" doesn't help either. – Tal Ben-Porath Sep 05 '19 at 11:16
