I have encountered what I shall presume is a bug: setting $RecursionLimit repeatably crashes the Mathematica 10 kernel:

$RecursionLimit = 50    (* kernel crash *)

Further, setting $RecursionLimit = 20 produces a malformed Suggestions Bar containing text code starting with:

Manipulate`Dump`eDynamicModule[ . . .

I am running version on Windows 7. Please report behavior on your system.

    $\begingroup$ Not reproducing the crash on mac, seeing "interesting" things with the suggestions bar, though. $\endgroup$ – rcollyer Jul 14 '14 at 1:52
  • $\begingroup$ @rcollyer Would you try some other values, e.g. 40? $\endgroup$ – Mr.Wizard Jul 14 '14 at 1:54
  • $\begingroup$ Not a pretty result, but no crash. $\endgroup$ – rcollyer Jul 14 '14 at 1:55
  • $\begingroup$ I take it back. It does cause a problem, but only after using a different command in other cell. Right after issuing $RecursionLimit = 50 there is no problem as far as anything showing in console. (but the damage has allready been done internally I assume). $RecursionLimit = 20 causes no problems. $\endgroup$ – Nasser Jul 14 '14 at 1:56

    $\begingroup$ The issue happened both in 10.0 and 9.0.1: screenshot. $\endgroup$ – Silvia Jul 18 '14 at 6:33

Not an answer but I just wanted to observe that the $RecursionLimit info box (whatever that is called) has a formatting error on my Mac:

Update halirutan: When I set $RecursionLimit to say 30, then hover the symbol and click on the information $i$, I sometimes get more than only wrong formatting:

  • $\begingroup$ I see the same formatting error under Win7 x64. $\endgroup$ – Alexey Popkov Jul 14 '14 at 6:09

    $\begingroup$ Same formatting error under Linux. This is how they search and replace hahaha $\endgroup$ – Yi Wang Jul 14 '14 at 15:11
  • $\begingroup$ This rebranding error is actually everywhere in the hover message, when originally Mathematica is mentioned. For example, do the same for $Version or $OperatingSystem and find a similar (slightly different) error. I think the problem is StyleBox support in hover message is broken. $\endgroup$ – Yi Wang Jul 14 '14 at 15:14
