For 23_containers/unordered_set/requirements/exception/basic.cc the
situation is a little bit different. During the fifth invocation of
run_steps_to_limit(i, container, f) about 32 GByte are allocated.
Interesstingly the output seems right:
N10__gnu_test12functor_base12insert_pointISt13unordered_setIN9__gnu_cxx17throw_value_limitESt4hashIS4_ESt8equal_toIS4_ENS3_21throw_allocator_limitIS4_EEELb1ELb0EEE
end count 7

But the container structure is nonesense after the call:
_M_bucket_count = 4294967291
_M_element_count = 77
_M_rehash_policy = {static _S_growth_factor = 2, _M_max_load_factor = 1,
_M_next_resize = 18446744073709551615}

I hope that helps.
