AFAIK Maple 6 should not do this. Prior to Maple 6, on 32-bit computers
a polynomial could have at most 2^16 terms. Now the limit should be 2^25.
Thus you are likely to run out of time or physical memory before getting
an "object too large" message. Can you estimate the number of terms your
expanded expression should have?
