[Octave-bug-tracker] [bug #53713] test failure "speed.m" in Octave 4.3.91

[Rik]

Follow-up Comment #6, bug #53713 (project octave):

The warning message says that all times were zero.  Can you help debug that? 
Try


dbstop speed 246
[order, n, T_f1, T_f2] = speed ("sum (x)", "", [100, 1000], "v = 0; for i =
1:length (x), v += x(i); endfor");


This will stop at line 246.  Type


__tnew
__torig


to inspect the two timings.  Are they really all zeros?  If not, do dbnext
twice (maybe 3 times) until you have passed


    zidx = (__tnew < 100*eps | __torig < 100*eps);


type 


zidx


Is this all ones?


If you can write back to this report the value of __tnew, __torig, and zidx we
can investigate.
