Excel 2013 crashes when using function names for worksheets

Problem

If you create a new Excel file and, before saving it, rename a worksheet to a name starting with "Delta(" or certain other function names, Excel 2013 crashes. If you save the file before renaming the worksheet, the problem does initially not occur. However, if you open such a file while think-cell is active, Excel 2013 crashes.

Excel 2013 also crashes if you create a reference to an existing worksheet whose name Excel 2013 recognizes as a function name from Microsoft's Analysis ToolPak (ATP).

This is caused by a bug in Excel 2013. The problem can be reproduced without think-cell by creating a new file and, before saving it, renaming the worksheet to "Delta(…".
