Actually, the patch is not sufficient to fix the issue. When building the 3.2.2 
version on macOS 13 arm with the command line tools from Xcode 15 it breaks 
with:

… many, many ld warnings about pointer alignment similar to the next 3
ld: warning: pointer not aligned at _THREADVARLIST_$CHARSET+0xC from 
/opt/local/var/macports/build/_Users_michael_Developer_macports-ports_lang_fpc/fpc/work/fpcbuild-3.2.2/fpcsrc/rtl/units/x86_64-darwin/charset.o

With the command line tools of Xcode 14 it runs through without any warning nor 
error. Would a patch from this commit 
(https://gitlab.com/freepascal.org/fpc/source/-/blob/82dd70e72f3ab33b1b8737f743e1cdd009d9c8a1/compiler/x86_64/cpupara.pas)
 help?

Michael.
