Configuration command:
../combosrc/configure --prefix=$CWD/installdir --target=h8300-elf --disable-nls
--disable-threads --disable-tls --enable-checking=release
--enable-languages=c,c++ --with-newlib --enable-multilib --enable-lto
--disable-shared --enable-static --disable-libstdcxx-pch
--without-libstdcxx-zoneinfo --with-system-zlib --with-pkgversion="$PKGVER"

And here comes the interesting part – this happens when I build gcc using
combined source tree as described here: https://gcc.gnu.org/simtest-howto.html.
When I build gcc & Co "sequentially" from my local git repositories, i.e.
binutils in the first step, C cross compiler in 2nd, newlib in 3rd and finally
C and C++ cross comiler in the 4th step everything seems to be fine.
Configuration command in the 4th step is exactly the same as mentioned above.

If the compiler crashes then that's a compiler bug, not a library bug.

Reassigning to rtl-optimization but that might not be accurate.

--- Comment #2 from Jeffrey A. Law <law at gcc dot gnu.org> ---
Jon's right.  This would be a compiler bug.  Note however that we have never
supported libstdc++ on the H8, but even so the compiler shouldn't be faulting
like that.
