I changed the code slightly to make this benchmark file, bm_toeplitz.m

runs = 5;

cumulate = 0; b = 0;
for i = 1:runs

  tic;
    for j = 1:620
      for k = 1:620
        b(k,j) = abs(j - k) + 1;

## Total time
cumulate

Results are the same as the simpler loop test, about a 25% slowdown from 4.2 to 4.4.

4.2.1	4.4.1	5.1.0
10.544	13.052	13.481

I compiled 4.2.2  and can confirm that (on i7-2600k):

4.2.2: cumulate =  17.162

6.0.0 (dev: 2c4759c8239c @): cumulate =  21.816
