Yes, I get the same results exactly, unless I build
with ares and without debug, then the crash is in :
Curl_readwrite() at transfer.c:611
  data->info.contenttype = malloc(len + 1);

( Can't alloc 10 bytes? )

It also depends on the particular set of url's , if I try
to get the images from aol's homepage, then the crash moves:

Without debug:
Curl_disconnect() at url.c:1325 Curl_safefree(conn->user);

With debug:
Curl_llist_remove () at llist.c:125

For what it's worth, I also tried linking against electric fence,
which crashes at Curl_resolv_unlock () at hostip.c:339
339 dns->inuse--;

 ...but that doesn't make much sense to me.
