Bug 2183668

User-Agent:       Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/111.0.0.0 Safari/537.36
Build Identifier: 

On Fedora 38 starting with gcc-13.0.1-0.6.fc38.x86_64 thru (at least) gcc-13.0.1-0.8.fc38.x86_64, I'm seeing a build error when building either gdb-13.1 (from Fedora) or upstream gdb.  I see the same problem on rawhide and have tested gcc versions up to gcc-13.0.1-0.11.fc39.x86_64. (At the time of testing, the build wasn't complete for all architectures, but it had completed for x86_64; I downloaded the necessary packages from koji and installed them by hand.)

On both Fedora 38 and rawhide, I did not see the build problem with gcc-13.0.1-0.5.

The build error that I'm seeing is:

Reproducible: Always

Steps to Reproduce:
1.

cd /tmp

2.

git clone git://sourceware.org/git/binutils-gdb.git

3.

rm -rf build ; mkdir build ; cd build

4.

../binutils-gdb/configure --with-separate-debug-dir=/usr/lib/debug \
  --with-data-directory=/usr/share/gdb \
  --disable-{binutils,gas,ld,gprof,gold,sim} \
  CFLAGS="$(rpm --eval '%{build_cflags}')" \
  CXXFLAGS="$(rpm --eval '%{build_cxxflags}')" \
  LDFLAGS="$(rpm --eval '%{build_ldflags}')" \
  --enable-targets=s390-linux-gnu,powerpc-linux-gnu,arm-linux-gnu,aarch64-linux-gnu,amd64-linux-gnu

5.

V=1 make -j$(nproc)

(Due to use of the -j flag, you may have to scroll up to find the error/warning.)
Actual Results:  
Build does not complete successfully.  Error output is shown in "Details", above.

Expected Results:  
A successful build.  As noted earlier, I am able to get a successful build when using gcc-13.0.1-0.5 or by adding -Wno-stringop-overflow to CFLAGS and CXXFLAGS.  I'm currently using -Wno-stringop-overflow as a workaround for the Fedora gdb package on f38 and rawhide.
