--- Comment #1 from Eric Botcazou <ebotcazou at gcc dot gnu.org> ---
What does 'gcc -v' print exactly?  It looks like you're trying to bootstrap a
64-bit compiler with a 32-bit toolchain.

This is still a problem, tested at commit
217d5beaff9987a9845155fc796322b5f8bb876d, Dec 17th, 2020

Starting with the same gcc (7.3.0) as before, but invoked with CC="gcc -m64" to
make sure that we're building with a 64-bit toolchain -- leads to:

Please try without --disable-checking or with --enable-checking=release.

Thanks! configuring with  --enable-checking=release  allowed it to compile.

The final configure that I used was:

../gcc-master/configure prefix=/opt/gcc --disable-werror
--enable-checking=release CC="gcc -m64" CXX="g++ -m64"
--build=sparcv9-sun-solaris2.11 --with-gnu-as --with-as=/opt/bin
utils/bin/as --without-gnu-ld --with-ld=/usr/bin/ld
build_alias=sparcv9-sun-solaris2.11 --enable-languages=c

There was one hiccup -- the install step wants to compile:

cc1plus: error: -Werror=format-diag: no option -Wformat-diag


however it appears to be using whatever g++ was already installed, and that g++
(7.3.0) is too old to know "-Wno-error=format-diag".

The answer was to "gmake -i install" which managed to get a new g++ installed,
and then "gmake install" again with the new g++ on the path to get an
error-free install.

Final result is:

You're welcome.  We strongly discourage to configure with --disable-checking
because the compiler will generally not stop in cases where it is confused.

The build should not segfault with it though, so keeping the PR open.
