[NTG-context] Font memory issues ?

Oh, d**mn.
I just had a brainwave.

 From Web2c's tex.ch comes the following:

   @!inf_font_mem_size = 20000;
   @!sup_font_mem_size = 2000000;

So font_memory cannot be set larger than 2000000 and not smaller
than 20000. Out-of-bounds sizes are silently folded back in line,
but that happens after the variable expansion is complete. That's
why the debug switch still reports the values from texmf.cnf.

So the actual problem here is the web2c runtime code inside TeX.

You can recompile with a larger sup_font_mem_size, I guess. But
otherwise you are out of luck.
