The VM has issues to cope with function constants like pi and a material
number of existing variables in scope.
a) small number of variables work fine
========================================
function retval = test3()
for i=1:1000
pp = cos((360*rand(1,1) - 360*rand(1,1)).*pi./180.0);
endfor
retval = pp;
whos;
endfunction
clear test3; __enable_vm_eval__(1); test3()

==== ==== ==== ===== =====
i 1x1 8 double
pp 1x1 8 double
f retval 1x1 8 double
Total is 3 elements using 24 bytes
a) large numbers of variables causes VM error
=============================================
