Signal 11 was raised in the native code while using update SM through xml

I am getting the below error when I am requesting SM to update the approval groups through xml soap request, which I am sending it through the invoke method in the OO 10, I get this error only when I am passing the changeID in the xml.

A signal 11 was raised in native code. Client terminated. Error: Win32 Exception: 0xC0000005 (instruction 0x101697C4 while reading address 0x00000000)

I dont get any error when I pass the change id through someother variable and include it in the xml, I get the response, but the SM would not be updated in this case.

Can any one or anybody has faced similar kind of issues?

Please reply at the earliest
