how to fix custom fastcgi program written in C - c

Question

This is my program:
#include "fcgi_stdio.h"
#include <stdlib.h>
int main(){
while (FCGI_Accept() >= 0){
FCGI_printf("Content-Type:text/html\r\n\r\n");
FCGI_printf("<h1>Test</h1>\n");
}
return 0;
}
These are the options I added to the apache config for the virtual host I'm working with:
SetHandler fastcgi-script
Options +ExecCGI
I also have the following line in the same apache config file:
LoadModule fastcgi_module modules/mod_fastcgi.so
I followed directions at FastCGI script can't find libfcgi.so.0 in Apache 2.4.6 and mod_fastcgi to compile my program.
If I execute the compiled program directly, I receive the familiar "segmentation fault" on screen. When I try executing it via the server at http://127.0.0.1/a.out, I get an internal server error and the following in the error_log:

Its basically telling me that apache is attempting to start the program a few times but the program returns segmentation fault.
The result I was expecting was the word Test in bold in a web browser.
How do I fix my program to make it compatible with fast-cgi so that I can execute it via a web browser?
I don't want to resort to the slow CGI interface which is why I'm trying to use functions beginning with FCGI.
