>>> DT = dt.Frame(range(300000000))
>>> DT[:, "A"] = dt.str32(f[0])
ValueError: The size of new_strbuf does not correspond to the last offset of new_offbuff: expected 2588888890, got 441405242

The total size of string data in the column exceeds int32, but the converter is not smart enough to automatically convert to str64.
