            Bug ID: 94139
           Summary: GCC9.2.0 build GCC8.2.0 break
           Product: gcc
           Version: 9.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: sanitizer
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kangshan0910 at hotmail dot com
                CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,

  Target Milestone: ---

Gcc8.2.0 will fail to be built after glibc is updated from 2.30 to 2.31.

Here is the reproduce steps:
1. Download gcc-8.2.0 source code from
ftp://ftp.fu-berlin.de/unix/languages/gcc/releases/gcc-8.2.0/gcc-8.2.0.tar.gz
or ftp://ftp.gwdg.de/pub/misc/gcc/releases/gcc-8.2.0/gcc-8.2.0.tar.gz or
https://ftp.gnu.org/gnu/gcc/gcc-8.2.0/gcc-8.2.0.tar.gz
2. Unzip the package
#cd gcc-8.2.0
#./contrib/download_prerequisites
#./configure --disable-multilib --enable-checking=release
#make defconfig
#make clean
#make -j4

After a while, the following error will occur.

SO use GCC 8.4.0 instead?

This is a benchmark from phoronix
(https://openbenchmarking.org/test/pts/build-gcc-1.1.2). The benchmark uses
gcc-8.2.0.

We can't retroactively fix already released versions.  For bugfixes we have
release branches from which we periodically create new releases.
