First off, hello to everyone. I wanted to express my appreciation for
such a solid program and library set. Truly a great resource to work with.

I came acrossed a problem that I was hoping somebody here could help me
with, however. I've search Google, and the curl mailing lists and
couldn't seem to find anything. I'm trying to use the --dump-header
option on the command line curl client with the FTP protocol. On my
HP-UX systems it works fine. However, on my Linux based platforms
(using glibc) I get the following crash at the end of the program:

*** glibc detected *** corrupted double-linked list: 0x0806f2f8 ***
Aborted

The dump file is written correctly and I can get the ftp response I am
looking for whether it is a directory listing or the actual file.
However, the return code ends up being 2 indicating a problem instead of
a successful transaction, throwing my script off... There are other
cases where a 2 error should be caught however, so I can't just ignore
the return code.

I have tested this using 7.14.0 and 7.12.3 on Fedora with the problem
showing up and 7.13.0 on HP-UX with no problems.

I also ran the curl client against valgrind's memcheck tool and got the
following stack trace and similar reports:
==4615== Invalid read of size 2

Any help would be much appreciated, even if it was a "look here for the
possible cause."

Ben
