# Setting $RecursionLimit crashes Mathematica 10 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:

ManipulateDumpeDynamicModule[ . . .


I am running version 10.0.0.0 on Windows 7. Please report behavior on your system.

• Not reproducing the crash on mac, seeing "interesting" things with the suggestions bar, though. – rcollyer Jul 14 '14 at 1:52
• @rcollyer Would you try some other values, e.g. 40? – Mr.Wizard Jul 14 '14 at 1:54
• Not a pretty result, but no crash. – rcollyer Jul 14 '14 at 1:55
• 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. – Nasser Jul 14 '14 at 1:56
• The issue happened both in 10.0 and 9.0.1: screenshot. – 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:

• 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. – Yi Wang Jul 14 '14 at 15:14
