--- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Confirmed with trunk. gcc 7 and 6 show the output quoted above for 5.5.0,
with:
"confused by earlier errors, bailing out"
The trunk ICE is here:
Program received signal SIGSEGV, Segmentation fault.
check_local_shadow (decl=decl@entry=0x7ffff19d5b48) at
../../src/gcc/cp/name-lookup.c:2682
2682 if (scope->kind == sk_class
(gdb) p scope
$1 = (cp_binding_level *) 0x0
The segfault started somewhere between r248121 (unaffected) and r248123
(affected), probably r248123, so CCing Nathan.
Prior to that, the:
"confused by earlier errors, bailing out"
comes from this assertion failing in pop_local_binding:
405 gcc_assert (binding->type == decl);
masked in release builds by the "confused by earlier errors, bailing out"
post-error-ICE-handler. This failure started somewhere between r180695
(unaffected) and r180713 (affected).
