An experiment:
OK:
(%i1) for j : 1 thru 200 do (for i : 1 thru 200 do z : (random(10) * x /
42 - random(10)
* y / 8+ random(100)));
(%o1) done
Not OK:
(%i2) for j : 1 thru 200 do (for i : 1 thru 200 do sign(random(10) * x /
42 - random(10)
* y / 8+ random(100)));
Maxima encountered a Lisp error:
Error in PROGN [or a callee]: Bind stack overflow.
Automatically continuing.
To reenable the Lisp debugger set *debugger-hook* to nil.
Maybe all this is coming from the 'dgr' or 'visiblep' (defined in
db.lisp)?
