Comment (by kencu):

 well, building libgcc7 with this:
 {{{
 --with-default-libstdcxx-abi=0
 }}}
 certainly did not seem to help. {{{cmake}}} just gives the error during
 bootstrap now, and won't even build:
 {{{
 cmake(5351) malloc: *** error for object 0xa0b863dc: Non-aligned pointer
 being freed
 *** set a breakpoint in malloc_error_break to debug
 cmake(5351) malloc: *** error for object 0xa0b8636c: Non-aligned pointer
 being freed
 *** set a breakpoint in malloc_error_break to debug
 loading initial cache file
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_cmake/cmake/work/cmake-3.16.4/Bootstrap.cmk/InitialCacheFlags.cmake
 ./bootstrap: line 1676:  5351 Bus error
 "${cmake_bootstrap_dir}/cmake" "${cmake_source_dir}"
 "-C${cmake_bootstrap_dir}/InitialCacheFlags.cmake"
 "-G${cmake_bootstrap_generator}" ${cmake_options}
 ${cmake_bootstrap_system_libs} "$@"
 }}}

 so -- on to other ideas I guess.
