An update: I now tried it again in aldor -gloop:
%4 >> binomial(2^10, 2^5)
() @ AldorInteger
Comp: 10 msec, Interp: 10 msec
%5 >> binomial(2^10, 2^5)
() @ AldorInteger
Comp: 0 msec, Interp: 10 msec
%6 >> binomial(2^20, 2^5)
() @ AldorInteger
Comp: 10 msec, Interp: 0 msec
%7 >> binomial(2^20, 2^8)
() @ AldorInteger
Comp: 10 msec, Interp: 30 msec
%8 >> binomial(2^20, 2^9)
() @ AldorInteger
Comp: 0 msec, Interp: 60 msec
%9 >> binomial(2^20, 2^10)
() @ AldorInteger
Comp: 10 msec, Interp: 400 msec
%10 >> binomial(2^20, 2^11)
() @ AldorInteger
Comp: 0 msec, Interp: 1150 msec
%11 >> binomial(2^20, 2^13)
() @ AldorInteger
Comp: 0 msec, Interp: 18000 msec
So, I'd guess it's a problem of the algorithm, not Aldor.
