The code I sent earlier is multi-single.c from doc/examples & my point is that the code hangs, if its used with libcurl, thats built with async enabled. What I need is, help in figuring out if I'm missing any build settings or curl options?

Are you saying that the problem in not reproducible on linux, built with async (C-ARES or THREADS)?
