Segmentation fault when including <boost/asio.hpp> in multiple compilation units on MacOS with GCC #1484

Minimum working example to reproduce

I have two source files that both #include <boost/asio.hpp>. Both files use source_location. When I call the function (that uses source_location), it works as expected. When I call the one in the other (that also uses source_location) compilation unit , the program crashes. This happens only on MacOS (built for arm64 with GCC - I've tried with both 11.4, 13.1 and 14.1).

Using clang I do not see the issue.

However, using #include <source_location> instead of #include <boost/asio.hpp>, everything works fine.

I also noted, that if I just #include <boost/asio.hpp> in one file, but #include <source_location> in both files, everything works fine.

So the issue seem to arise when #include <boost/asio.hpp> in several different compilation units.

Example zip

I have also attached the example. It should build out of the box (but might require you to change the boost include path in the CMakeLists.txt from /usr/local/boost_1_82_0 -> your own path).
