Hi all!

Calling curl_global_init() and curl_global_cleanup() (as demonstrated in the
attached source) results in memory leaks (at least according to valgrind) on
my Debian Testing VM, and my Fedora 11 (up-to-date) VM, and also possibly on
my Mandriva Cooker host.

I am invoking valgrind like this:

{{{{{{{{{{{{{
#!/bin/sh
valgrind --tool=memcheck --leak-check=full --leak-resolution=high \
    --num-callers=20 --log-file=val.txt --leak-check=full \
    --show-reachable=yes ./curl-test
}}}}}}}}}}}}}

And am getting the following output:

{{{{{{{{{{{{{

My libcurl packages on Debian are:

Any help would be appreciated.
