These tests try to find out the practical limits of the length of list in (apply + list). I used make-list to construct a list of one million zeros and invoked the above apply. If it worked, I tested no further; if it crashed, I read the error messages and when necessary tested with shorter lists.

These tests were done on a 64-bit Linux system.
