May I suggest another approach? Install some Linux (e.g. Debian) distribution on your build system. If your build machine is a desktop, it could be as cheap as buying a new SSD disk (they cost less than 120€ or 150US$) and install a dual boot on your hardware desktop. I assume some familiarity with Linux. Once Linux is installed, compile GCC 15.1 from its source code (it can be configured as a cross-compiler) and use it. Some Linux distributions are even packaging cross-compilers based on GCC. If you suspect a bug in GCC itself (and are willing to improve GCC itself) configure it with debugging enabled. You need to configure then build GCC from its source code in a different build directory that the source code directory. In some cases writing your GCC plugin (inspired by ideas from https://arxiv.org/abs/1109.0779 and obsolete code from https://github.com/bstarynk/bismon and the http://www.starynkevitch.net/Basile/bismon-chariot-doc.pdf ...) could be worthwhile. I did wrote that code (when working at CEA, see www.cea.fr) but now I am retired and don't maintain it anymore. Details depend on the size and complexity of the source code your are building with GCC. Regards from near Paris in France. NB.
