This looks to be not a symbol but type name. So I can not locate it with nm.
But I have found it directly in the binary. Line containing this text looks like

.... ^@exact_unsigned_base_helper<sizeof(unsigned int) *
8>^@uint_t<32>^@low_bits_mask_t .......

Do you think the problem is in clang? Could you point out some
specification, so I can reference it while contacting clang people.

Thanks,
