Brett, you could verify that by applying the following patch and testing if the problem persists:
diff --git a/lib/asyn-thread.c b/lib/asyn-thread.c
index 0adac40..4ae904c 100644
--- a/lib/asyn-thread.c
+++ b/lib/asyn-thread.c
@@ -209,12 +209,8 @@ int init_thread_sync_data(struct thread_sync_data * tsd,
  memset(tsd, 0, sizeof(*tsd));

  tsd->port = port;
-#ifdef CURLRES_IPV6
  DEBUGASSERT(hints);
  tsd->hints = *hints;
-#else
- (void) hints;
-#endif

  tsd->mtx = malloc(sizeof(curl_mutex_t));
  if(tsd->mtx == NULL)

If this fixes the problem, you are experiencing the same bug that I have. As I said in the other thread, please assume this fix might break other things (non-http protocols, etc), as I don’t know all of the potential side effects.

HTH,
Fabian
