Yes, if it makes any difference for a --with-dwarf2 bootstrap, this means that gcc and libgcc had different views of the EH scheme of the compiler. The --disable-sjlj-exceptions breakage is worth investigating separately, so please create a PR with Bugzilla (https://gcc.gnu.org/bugzilla) for it. -- Eric Botcazou
