That is a sure sign of a firmware bug.  
I'd upgrade the firmware of the router.

Hi,

Seems a bug. Upgrade ISO version:

I am sharing with you Software Installation and Upgrade Procedures:-
This section covers these topics:
Step 1: Select a Cisco IOS Software Image
Step 2: Download the Cisco IOS Software Image to the TFTP/FTP Server
Step 3: Identify the Router File System to Copy the Image
Step 4: Prepare for the Upgrade
Step 5: Verify that the TFTP/FTP Server has IP Connectivity to the Router
Step 6: Copy the IOS image to the Router
Step 7: Verify the Cisco IOS Image in the File System
Step 8: Verify the Configuration Register (If required)
Step 9: Verify the Boot Variable
Step 10: Save the Configuration and Reload the Router

Configure Boot Variable as :

boot-start-marker
boot system flash:/<new file name>
boot-end-marker
