Curious. This error suggests you have called ajMemCalloc with a request for an 
array of zero (or negative) length.
I suspect you have exceeded the size of an integer. It does not look like a 
floating point problem.

Macros that call ajMemCalloc include:

AJCALLOC(count, nbytes)
AJCALLOC0(count, nbytes)

In each case, "nbytes" is the value that was not a positive integer.

In EMBOSS memory handling nbytes is of type ajlong. It may be you need to store 
the database size in a larger integer datatype, or perhaps some automatic 
conversion to int is happening.

Let me know if you need more clues.
