After a week, we are able to compile with TCC but it fails to link.
Patch is attached to this msg.

Here it is the proof:

% cat hello.c
#include <stdio.h>

int main(){
        printf("hello, world!\n");
        return 0;
}

% tcc -c hello.c
% tcc -o hello hello.o
% ./hello
Bus error (core dumped)
% cc -o hello hello.o
% ./hello
hello, world!

So we guess that linking is broken.
