Apparently GCC doesn't like "uint8_t* one_byte_content_ = nullptr;", the pointer
contains bogus data when "delete[]" is called in the constructor (for
non-"special_flattening_" cases, where one_byte_content_ should be unused and
just carry its nullptr initialization around). 

Verified the fix locally, landing with NOTRY to greenify the tree.
