Hi,

I'm using the 7.7 version of the curl library to perform an ftp operation.
In the case where the host does not exist, I get a segfault. This is part
of the stack trace:

----------------------------
This GDB was configured as "i386-redhat-linux"...
Core was generated by `./imgman_mgr'.
Program terminated with signal 11, Segmentation fault.

-------------------------------------------------

The ftp pointer in Curl_ftp_disconnect is NULL. I can avoid the core dump
by checking the ftp pointer, but don't know why that pointer is NULL. Anyone
have any clues?

Thanks!

Ravi
