--- Comment #2 from James Greenhalgh <jgreenhalgh at gcc dot gnu.org> ---
Fails for me on trunk and 5.3. Trunk backtrace for an aarch64-none-elf compiler
(but the target doesn't matter, same fail on arm-none-eabi and a
not-quite-trunk x86_64-none-linux-gnu):

foo.cpp: In function ‘int main()’:
foo.cpp:7:23: internal compiler error: tree check: expected record_type or
union_type or qual_union_type, have array_type in build_special_member_call, at
