Bug#1022991: libc6: broken y2038 support in fstatat on mips64el
Package: libc6
Version: 2.35-1
Severity: critical
Tags: upstream
Justification: breaks unrelated software
On mips64el the fstat/fstatat/lstat functions return EOVERFLOW when they
are called on files with a mtime, atime or ctime that can't be
represented within a 32-bit time_t. This should not happen as time_t is
64-bit on mips64el. This is a regression from glibc 2.34 and can be
reproduce with:
(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:~$
This breaks unrelated software, for instance the build of gcc-12 on the
build daemons:
