This is an issue specifically with compilers configured with
--with-long-double-format=ieee. It also shows up in gcc 10, 11, and 12 though
at a different line #. I am only seeing it on a system where the distro
(Fedora 36) tools were also built with --with-long-double-format=ieee.
My trunk compiler was configured was with --enable-languages=c,fortran,c++
--with-cpu=power9 --enable-bootstrap --disable-multilib
--with-long-double-format=ieee
Note: bootstrap part doesn't matter as a non-bootstrap compiler also ICEs the
same way.
The distro compiler was gcc version 12.1.1 20220507 (Red Hat 12.1.1-1) (GCC)
and was configured with: ../configure --enable-bootstrap
--enable-languages=c,c++,fortran,objc,obj-c++,ada,go,lto --prefix=/usr
--mandir=/usr/share/man --infodir=/usr/share/info
--with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-shared
--enable-threads=posix --enable-checking=release
--enable-targets=powerpcle-linux --disable-multilib --with-system-zlib
--enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object
--enable-linker-build-id --with-gcc-major-version-only
--enable-libstdcxx-backtrace --with-linker-hash-style=gnu --enable-plugin
--enable-initfini-array
--with-isl=/builddir/build/BUILD/gcc-12.1.1-20220507/obj-ppc64le-redhat-linux/isl-install
