I created a C++ wrapper to libcurl (!= curlpp) and worried about memory leaks

[Patrick Louis]

Dear libcurl mailing list readers,
I'm working on a little c++ wrapper for libcurl which resembles a lot
the python2 module mechanize.Browser()
Here is the link to the library: https://github.com/venam/Browser
It really makes some tasks look relatively easy compared to the
libcurl or curlpp way of doing.
However, I'm not sure about how I managed to not leak memory.
I tried to put in all the destructors the "free" functions but
running valgrind with --leak-check=yes
shows me that there's some bytes that are leaked during the process.
I'm not an expert in debugging but I see that some leaks are from
libcrypto.

If someone could clear my mind about that or just lead me to a better
way to do things.
(This email is linked with the valgrind logs.)

Thank you for your prompt support,
Patrick Louis

Without your exact code it is hard to tell, but it seems to be an curl_slist
list that you created with curl_slist_append() that's left allocated.

If you build with debug symbols left, valgrind will tell you the exact source
code line that did it.

Thanks a lot.
Your answer resolved my whole problem.
I reviewed the whole places where I used the curl_slist_append() and
directly freed the headers after use.
Now I have 0bytes leaked, fabulous.
I'm really glad that "the" Daniel Stenberg replied directly to me, I'm
a big fan of your works and included in my library a form grabber that
outputs exactly like the one you did in perl.

I'll push the updates to my git repo tonight (in 4-5 hours)

Again, thanks, you are an inspiration for the youth!
