Mysterious Redis C core dump - c

Question

I am currently running a C program calling a Redis Server instance. After the 1020th iteration, it always bombs with:
Redis Connect 1021 Error: System error Segmentation fault (core
dumped)
Ugh. Something tells me one of the pointers decided to go wild. Can anyone help here? I am using the current version of Ubuntu Linux

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
#include "hiredis.h"
void redisTest(void) {
redisReply *reply;
long int i;
// Start measuring time
clock_t start = clock();
// For local connections:
//redisContext *c = redisConnect("127.0.0.1", 6379);
redisContext *c = redisConnect("localhost", 6379);
// For connections to a remote Redis server:
//redisContext *c = redisConnect
// ("ec2-**-**-***-**.compute-1.amazonaws.com", 6379);
if (c->err) {
printf("Error: %s\n", c->errstr);
}else{
printf("Connection Made! \n");
}
// Get all keys for testing
//reply = redisCommand(c, "keys %s", "*");
reply = redisCommand(c, "lrange EUR 0 10", "*");
if ( reply->type == REDIS_REPLY_ERROR )
printf( "Error: %s\n", reply->str );
else if ( reply->type != REDIS_REPLY_ARRAY )
printf( "Unexpected type: %d\n", reply->type );
else {
for ( i=0; i<reply->elements; ++i ){
printf( "Result:%lu: %s\n", i,
reply->element[i]->str );
}
}
printf( "Total Number of Results: %lu\n", i );
// Output Elapsed time
printf ( "%f Seconds\n", ( (double)clock() - start ) /
CLOCKS_PER_SEC );
redisFree(c);
freeReplyObject(reply);
}
int main(void) {
int i = 0;
for(;;) {
printf("\n\nRedis Connect %d\n",i++);
redisTest();
}
}
Update: I added redisFree() as suggested by others (thanks for that). This still core dumps but after 28233 iterations.
