  yes. With the same program and sa=sb=31225173 (same product size), GMP 4.3.2
  uses 1.6g (same memory) and GMP 5.0.0 uses 2.1g (slightly less than with
  unbalanced operands, but still more than 4.3.2).
  
Could you please try with larger MUL_FFT_TABLE2 (for example from the
repo or from the old release) and see if that helps?
