Hello,

on alpha, the gcc-13 build fails because the gnat compiler in the archive
is broken. When using an older version of gcc-13 with a working gnat version,
the build succeeds but fails when checking ALIHASH:

echo "checking ALIHASH ..."; \
p=gnat-13-alpha-linux-gnu; \
old=$(apt-cache show $p | awk '/^Provides/ {print $2}'); \
new=gnat-13-$(debian/ada/libgnat_alihash | sed 's/.*=//'); \
if [ $old = $new ]; then \
  echo "  -> matching alihash ($old)"; \
else \
  echo "  -> alihash mismatch: $old (installed), $new (built)"; \
  if [ xyes = xyes ]; then \
    exit 1; \
  fi; \
fi
checking ALIHASH ...
/bin/bash: line 5: [: too many arguments
  -> alihash mismatch: gnat-13-119f978a
gnat-13-97e8392b (installed), gnat-13-119f978a (built)
make[1]: *** [debian/rules2:1400: stamps/05-build-stamp] Error 1
make[1]: Leaving directory '/home/glaubitz/gcc-13-new/gcc-13-13.4.0'
make: *** [debian/rules:53: build-arch] Error 2

I have no idea what that hash value exactly means, but the bash syntax error
during the check looks suspicious, so I decided to report a bug.

FWIW, the build fully succeeds when disabling the check. I used this, to build
gcc-13_13.4.0-11 for alpha and then tried a fresh local build where again the
ALIHASH check failed.

that is fixed in the VCS.  I don't plan any updates before the 13.5.
release.

We believe that the bug you reported is fixed in the latest version of
gcc-13, which is due to be installed in the Debian FTP archive.

A summary of the changes between this version and the previous one is
attached.

Thank you for reporting the bug, which will now be closed.  If you
have further comments please address them to 1143972@bugs.debian.org,
and the maintainer will reopen the bug report if appropriate.
