(gdb) p newc
$1 = (const demangle_component &) <error reading variable: Cannot access memory
at address 0x0>
(gdb) p delc
$2 = (const demangle_component &) <error reading variable: Cannot access memory
at address 0x0>
1763 demangle_component *ndc = cplus_demangle_v3_components (new_str, 0,
&np);
1764 demangle_component *ddc = cplus_demangle_v3_components (del_str, 0,
&dp);
1765 bool mismatch = new_delete_mismatch_p (*ndc, *ddc);
(gdb) p new_str
$3 = 0x7ffff7009ea8 "_ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnernwEm"
(gdb) p del_str
$4 = 0x7ffff7009e70 "_ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnerdlEPv"
so we cannot demangle these? But we expect no failure. It should be trivial
to build in safety here, mine for that. I'll keep the PR open for the
failed demangle though.

tree-optimization/115232 - demangle failure during -Waccess
For the following testcase we fail to demangle
_ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnernwEm and
_ZZN5OuterIvE6methodIvEEvvQ3cstITL0__EEN5InnerdlEPv and in turn end
up building NULL references. The following puts in a safeguard for
faile demangling into -Waccess.

failure to demangle gracefully.
* g++.dg/pr115232.C: New testcase.
