I am running that same version in Windows 7 x64 and I haven't noticed a
problem like that. Try gdb curl (you'll need the cygwin gdb and
curl-debuginfo packages) then 'run args', then wait until it hangs and
CTRL+C, then 'thread apply all where'. Also try strace curl args.
Another thing you can do is let it hang 10 minutes to see if it
eventually exits on its own with an error.
