Weird execution path caused by stack buffer overflow
#include <stdio.h>
#include <string.h>

void fun1 ( char * input ) {
    char buffer[10];
    strcpy( buffer, input );
    printf( "In fun1, buffer= %sn", buffer );
}

void fun2 ( void ) {
    printf ( "HELLO fun2!n" );
}

int main ( int argc, char * argv[] )
{
    printf ( "Address of fun2: %pn", fun2 );
    fun1( "abcdefghijklmnopqrstuvx52x84x04x08" );
    return 0;
}
