I checked the version(s) for which the initialization bug is fixed: GCC-10.4 GCC-11.3 <<- so you are almost certainly seeing it with 11.2. GCC-12.1 GCC-13.1 (and current development ’trunk’). This was a very unusual case - we try to be backward compatible as much as possible, but the change was out of our hands. So, I’d recommend that you see if your “usual source” has an update - or, alternately, go to one of the ‘OSS distributions’ like Homebrew. HTH, Iain
