Dear All,

I wish to report a suboptimal behaviour in the mps_optim:

setting the initial state with wrong L (L=10 and there are 12 spins defined)

L=10;

init_state="local_quantumnumbers"

initial_local_S="0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5,0.5"

initial_local_Sz="0.5,-0.5,0.5,0.5,-0.5,0.5,-0.5,-0.5,0.5,-0.5,0.5,0.5”

produces a nasty segfault with no warning (in almost all other cases of setting something wrong a message explaining a nature of the problem is printed).

This is not a bug, but a nuissance.

Best,
