Getting SIGABRT from libcouchbase

I was running through my program and suddenly caught SIGABRT while using libcouchbase.
This was what I was getting from GDB Debugging
I've wrapped your libcouchbase in order to have similar interface with JAVA.

347 RSLTCODE CMBClient::Set( const uint64_t cas, const char* key, const char* value, const time_t* expiry)
348 {
349 libcouchbase_error_t error = LIBCOUCHBASE_SUCCESS;
350 libcouchbase_error_t callback_error = LIBCOUCHBASE_SUCCESS;
351 error = libcouchbase_store ( m_instance , (void*)&callback_error, LIBCOUCHBASE_SET, key, strlen(key), value, strlen(value), 0, (libcouchbase_time_t)*expiry, cas);
352 if ( error != LIBCOUCHBASE_SUCCESS )
353 {
354 fprintf(stderr, "Set Failed\n");
355 return CheckError(error);
356 }
357
358 libcouchbase_wait (m_instance);
359
360 return CheckError(callback_error);
361 }

Program received signal SIGABRT, Aborted.
