(http://curl.haxx.se/mail/lib-2006-02/0154.html) by adding the NTLM hash
function in addition to the LM one and making some other adjustments in the
order the different parts of the data block are sent in the Type-2 reply.
Inspiration for this work was taken from the Firefox NTLM implementation.
I edited the existing 21(!) NTLM test cases to run fine with these news. Due
to the fact that we now properly include the host name in the Type-2 message
the test cases now only compare parts of that chunk.

How To Track Down Suspected Memory Leaks in libcurl
===================================================
Single-threaded
Please note that this memory leak system is not adjusted to work in more
than one thread. If you want/need to use it in a multi-threaded app. Please
adjust accordingly.
Build
Rebuild libcurl with -DCURLDEBUG (usually, rerunning configure with
--enable-debug fixes this). 'make clean' first, then 'make' so that all
files actually are rebuilt properly. It will also make sense to build
libcurl with the debug option (usually -g to the compiler) so that debugging
it will be easier if you actually do find a leak in the library.
This will create a library that has memory debugging enabled.
Modify Your Application
Add a line in your application code:
curl_memdebug("filename");
This will make the malloc debug system output a full trace of all resource
using functions to the given file name. Make sure you rebuild your program
and that you link with the same libcurl you built for this purpose as
described above.
Run Your Application
Run your program as usual. Watch the specified memory trace file grow.
Make your program exit and use the proper libcurl cleanup functions etc. So
that all non-leaks are returned/freed properly.
Analyze the Flow
Use the tests/memanalyze.pl perl script to analyze the memdump file:
tests/memanalyze.pl < memdump
This now outputs a report on what resources that were allocated but never
freed etc. This report is very fine for posting to the list!
If this doesn't produce any output, no leak was detected in libcurl. Then
the leak is mostly likely to be in your code.
