# Dataset Crashes Information and Definition functions

Bug in 11.0.1 fixed in 11.1.0

Has anyone else noticed this odd function crash with Datasets. Try the following in a clean kernel.

ds = ExampleData[{"Dataset", "Planets"}]

?*


Repeated $RecursionLimit errors. Have to abort evaluation. ??*  Repeated$RecursionLimit errors.

Have to abort evaluation.

x = 1


Now both ?* and ??* complete. However if you select ds the \$RecursionLimit errors return and you must abort evaluation.

Version 11.0.1 Win 7 Ent

CASE:3861310

• ?ds is sufficient to trigger the problem. If there are two symbols, ?* is no longer equivalent to ?ds`. – Szabolcs Mar 15 '17 at 17:11
