That will make ct-lib happy, but I would worry the cure might be worse
than the disease.  If datafmt->maxlength represents the size of an
allocated buffer, increasing it without reallocating will write the NULL
to unallocated memory, with predictable unpredictable [sic] results.  

Looking forward to your results.
