snapwebsites | like CMS written entirely in C and Qt5 | Content Management System library

I have the following table definition:

I create a dot graph of dependencies for my Debian projects (see picture). The dependencies include redundant edges. I'd like to have a simpler graph without those redundant edges. I could calculate those on my own, but it's not too easy since I generate the .dot file in my CMakeLists.txt and .cmake extensions.

So I'm wondering whether there would be an option in dot or Graphviz to remove edges that are not required. So for example, the top snapwebsites project depends on csspp and advgetopt. Since the cspp package already depends on advgetopt, there is no need for the edge between snapwebsites and advgetopt.

In the digraph, this would mean:

I created a generic deleter template that can be used to create unique_ptr<>() sub-types allowing for a Deleter other than just delete ptr.

It works great with the default optimization flags (i.e. -O0), however, when I use -O3 the T & operator * () function, somehow, returns 0 instead of the f_pointer contents.

I would like to make sure that we agree that there is something wrong in the compiler and that my template is correct. The following is a complete piece of code that should compile as is under Ubuntu 16.04 and Ubuntu 18.04 and probably other versions as long as they support C++14 (see below for tested g++ versions).

I wrote some software in C++ and I'm trying to get the GDAX /products list for now (mainly as a test at this time.)

UPDATE: I wanted to add that the connection is actually to cloudflare and not directly to GDAX. So it is likely a problem with cloudflare and not directly GDAX servers.

Only, the BIO_do_connect() function returns -1 each time. It does not give me much to go on with it. I write the following in my log. So the main info is the error occurs on line 794 of s23_clnt.c...

OpenSSL: [336031996/20|119|252]:[]:[]:[]:[s23_clnt.c]:[794]:[(no details)]

I can tell that this means the TCP connection itself happens, but somehow it's not able to get an acceptable secure connection. I've see similar behaviors before when a machine would only some old encryption methods. But I checked with nmap and the connection definitely supports TLS 1.2. I ran the following command and got:
