ASSERT FAILURE (thread 23272): d:\drmemory_package\common\alloc_replace.c:3337: pre_us_heap == NULL || hashtable_lookup(&crtheap_handle_table, (void *)pre_us_heap) != NULL (failed to find pre-us heap)
```

Purpose:
I set up a small test application to detect any memory leaks or general heap corruption within some calls which are part of a (very sizable) in-house library, that utilizes a lot of threading operations.
