Follow-up Comment #22, bug #31287 (project octave):

The colon operator changes the size of an empty matrix:

octave:6> T=[]
T = [](0x0)
octave:7> T=T(:)
T = [](0x1)

This causes problems like:
octave:8> U=[]
U = [](0x0)
octave:9> T+U
error: operator +: nonconformant arguments (op1 is 0x1, op2 is 0x0)
