I suggest looking into the sources. In ocaml/stdlib/buffer.ml you can
read (near line 43)

    if b.position + more <= Sys.max_string_length
    then new_len := Sys.max_string_length
    else failwith "Buffer.add: cannot grow buffer"

So basically, you are hitting the limits of maximal string size (which
is 2^24 = 16777216 on 32 bits plateform).

Hence you cannot avoid it, except by switching to a 64 bits plateform.

You might change your algorithms - perhaps by keeping in memory a
vector of buffers or lines or paragraphs (whatever these are in your
application).
