Closed Issue: Corrupt XLS file goes into infinite loop [12556]

If I try to open a corrupt file, it goes into infinite loop, and then OutOfMemoryException. The only way is to kill the process.

```
FileStream stream = File.Open("c:\\temp\\corrupt.xls", FileMode.Open, FileAccess.Read);
IExcelDataReader excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
```

2nd line will go into infinite loop.

corrupt.xls is attached.

Appreciated any help. Please let me know if need more information. Thanks.
Comments: Resolved with changeset 86978: I've added a trap for the fat table reading zero for the next sector. I don't think this is allowed anyway, and this stops the infinite loop issue
