For the sake of demonstration in a class I wanted to use the line:

Histogram[Accumulate[RandomReal[{-1, 1}, 100000]], {1}, "Probability"]

to get a probability-like distribution of the random walk process. This worked for me on Mma7, 8, and 9 returning a reasonable probability-like histogram. As soon as I do it now (Mma 10.0.2, Win7) I get for several times the desired histogram. However, after several (about 10) trials I suddenly see the word "Histogram" appearing in red color, and the whole thing stops working, with a message that Histogram is obsolete. So, (i) what happened? and (ii) Could I repair it?

  • $\begingroup$ Same on Mathematica 10.0.0 Windows 8, no errors. Can you reproduce it just by running only that input line a couple of times in a fresh kernel? $\endgroup$ – 2012rcampion Mar 1 '15 at 20:24
  • $\begingroup$ Couldn't reproduce it with Mma 10.0.2 and Win7. $\endgroup$ – Karsten 7. Mar 1 '15 at 23:55

    $\begingroup$ I'm curious whether you can still reproduce this Alexei? I can get an error out of your command (MMA 10.2, Linux) but not after 10 trials, after a hundred or more, and my error is different as well. The error message is here $\endgroup$ – Jason B. Oct 14 '15 at 11:57
  • $\begingroup$ @Jason B I tried with Mma10.2 several possibilities, such as plain line given above, Table[...,{200}] and Do[...,{i,200}], where inside the operators there always was the above Histogram statement. No problem now. At least I did not notice with 200 repetitions. $\endgroup$ – Alexei Boulbitch Oct 19 '15 at 7:45

For Mathematica 10.2.0.0 there is no problem:
