Missing include for std::set in sync.cpp

Just a quick note that I also ran test on another Linux installation in VirtualBox and got following compilation error:

This error was fixed by adding #include <set> in sync.cpp (as message advises).

Additional variable for reproduction: must be configured with --enable-debug for this to occur on boost > 1.78

@victorsk2019

I see in your config.log that this is gcc 13.2, but I cannot find your boost version in there. Which version of boost are you using? You can find this with:

$ grep "define BOOST_VERSION " /path/to/include/boost/version.hpp
#define BOOST_VERSION 108200

[victorsk2019]

$ grep "define BOOST_VERSION " /path/to/include/boost/version.hpp

define BOOST_VERSION 108200

I get #define BOOST_VERSION 108400

[patricklodder]

Conditions for this to occur:

• boost > 1.78
• configuring with --enable-debug

I have reproduced this on gentoo x86_64 with boost 1.84 and macOS arm64 with boost 1.82.

The cleanest fix would be to write unit tests for #3313 and use that, as that fully takes care of this issue.
