James,

The error-message means that a "size_t" datatype isn't capacious
enough to hold the number of bytes in the data-portion of the
product-queue.  This is most likely because a "size_t" on your
system has only 32 bits.

It seems odd that a 64-bit system would have a 32-bit "size_t".
Would you mind checking this out?  I would start with the
following command:

    grep -rw size_t /usr/include
