Problem with compiling the server on a newer compiler

Hello,
I would like to gradually upgrade my server to a newer standard, but I’m currently facing the first problem, which is the compiler. I have FreeBSD 9.3 32-bit with GCC version 4.2.1. I tried to get compilation on new FreeBSD 13 and 14 with various available GCC versions. I even downloaded a pre-built VDI with FreeBSD 13 and prepared MySQL 5.6, but I keep running into the same issue.

First, the server compiled on the new FreeBSD required updated libraries. I solved this by statically linking everything I could into the binary. However, then a second problem appeared: the server prints:

The server does not start—it crashes immediately, and the syserr log is empty. This happens on all the newest GCC versions.

I’m not an expert in C++ or in this area, so I’m asking if it’s even possible to solve this. I’m not concerned about upgrading the code itself—that’s something I want to tackle later. My main goal is to maintain a functional compiler. I would really appreciate if someone could help me with this;
