Hello,

I work at a University and we use Maple 9.5, 13, and 16.  We have had problems with 13 and 16.  In this instance the program gets stuck at

for k from -N to N do
  e[k]:=g[k]/L2norm(g[k])
end do;

We left it run for 24 hours but it will not calculate e7. The program doesn't freeze but just seems to be in an endless loop. I have tried on multiple computers with different RAM/CPU configurations.

In Maple 9.5 this program...
