 If tcc is compiled with --with-selinux, it segfaults if using atexit in -run mode.

#include <stdio.h>
void cleanup(void) { }

int main(int argc, char **argv) {


    return 0;

CentOS 7.0 - built with gcc version 4.8.5
$ tcc -run atexit.c
Segmentation fault

Fedora 30 - built with gcc version 9.1.1
$ tcc -run atexit.c
tcc: error: undefined symbol '__dso_handle'
