Unable to run user defined program

I'm attempting to run my own program using the provided docker file. However, I'm running into issues doing so.

Here is the program (regex.c) in question:

#include <stdio.h>

int match(char* YYCURSOR) {
    char* YYMARKER;

    while (1) {
        char yych;

        yych = *YYCURSOR;
        switch (yych) {
            case 'a':
                goto yy2;
            default:
                goto yy5;
        }

yy2:
    ++YYCURSOR;
    yych = *YYCURSOR;
    switch (yych) {
        case 'b':
            goto yy2;
        case 'c':
        case 'd':
            goto yy7;
        default:
            goto yy4;
    }
yy4:
yy5:
    ++YYCURSOR;
    {return 0;}
yy7:
    ++YYCURSOR;
    {return 1;}

    }
}

int main() {
    char* test = "a";
    long res = match(test);


    return res;
}

Here is the modified Dockerfile:

FROM ubuntu:14.04
RUN apt-get update
RUN apt-get install -y clang-3.3 llvm-3.3 python3.5 python3-pip wget

Here is the error I get when running the modified Dockerfile:
