I have been able to reproduce by building gcc-12 on the eller.d.o
porterbox. It can be reduced to this simple test:

(sid_mips64el-dchroot)aurel32@eller:~$ touch -d 20390101 t
(sid_mips64el-dchroot)aurel32@eller:~$ chmod +x t
chmod: cannot access 't': Value too large for defined data type
(sid_mips64el-dchroot)aurel32@eller:~$ 

It seems related to the y2038 support in either coreutils or glibc.
