from openscad import *

s = square([5, 5])
ss = linear_extrude(s, height=5)
sss = ss.up(10).right(9).back(8)
ssss = sss.rotz(90)

print(ssss.origin)
inv = [[0, 1, 0, 9], [-1, 0, 0, -8], [0, 0, 1, -10], [0, 0, 0, 1]]
ori = align(ssss.origin, inv)

output([ssss, ori])

It will crash on line 10. Changing line 10 to ori = align(ssss, inv) will stop crashing.

Expected behavior Not crash.
