Confirmed on the development version of Octave as well. I only see this error when the right-hand side is a scalar (matrix of size 1).

Also can confirm that this is not the same as bug #31278. That bug was a regression of something that used to work in Octave 3.0.x. This one has never worked AFAICT. The error message for this bug in Octave 3.0.5 was

> iarray(1) = [];
error: operator =: no conversion for assignment of `matrix' to indexed `int64 scalar'
error: assignment failed, or no method for `int64 scalar = matrix'
error: evaluating assignment expression near line 10, column 11

There appears to be an error in assigning empty values to arrays of type other than double:

iarray = int64( [1 2] );
darray = double( [1 2] );

iarray(1) = [];
darray(1) = [];
% works, iarray & darray = [2] now

iarray(1) = [];
% error: A(I) = X: X must have the same size as I

darray(1) = [];
% works; returns empty 1x0 array

This seems closely related to open bug #31287: Certain assignments of empty arrays give errors (Matlab incompatibility), but perhaps not the same, since that bug involves assignments whos left-hand-sides are also empty (rather than becoming empty), and does not seem to depend on the data type.
