looks like there also is a problem in glibc. I only have coredumps with
glibc-2.2.4. After rebuilding curl with glibc-2.2.5 it doesn't dump core
anymore and I get the above error message.
debugging with gdb showed that connect() returns error 115 (EINPROGRESS,
Operation now in progress). So it is a curl bug - but might not be
reproduceable on your side because you are running another kernel and/or
another glibc.
The easiest solution would be to set the socket from non-blocking to
blocking (see the connect() manpage).
btw - thanks for your patch, ROCK Linux Changelog:

  - Improved/Fixed dependency detection
  - Updated curl-7.9.5 and fixed progress-bar (thanks to Daniel Stenberg)
