FINAL RESULTS:

data/pg-wait-sampling-1.1.1/collector.c:47:2:  [4] (format) snprintf:
  If format strings can be influenced by an attacker, they can be exploited,
  and note that sprintf variations do not always \0-terminate (CWE-134). Use
  a constant for the format specification.
	snprintf(worker.bgw_function_name, BGW_MAXLEN, CppAsString(collector_main));
data/pg-wait-sampling-1.1.1/collector.c:96:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(&newitems[i], &observations->items[j], sizeof(HistoryItem));
data/pg-wait-sampling-1.1.1/pg_wait_sampling.c:537:2:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
	memcpy(count, data, sizeof(*count));
data/pg-wait-sampling-1.1.1/pg_wait_sampling.c:550:3:  [2] (buffer) memcpy:
  Does not check for buffer overflows when copying to destination (CWE-120).
  Make sure destination can always hold the source data.
		memcpy(ptr, data, item_size);
