Runtime error 243 CoData strucure corrupted

Hi, i have a problem with the code i am running on a BL2600. It crashes with a runtime error 243. This has something to do with a CoData structure being corrupted. How can i determine what function is responsible or where in my program this happens.
My program writes the runtime error to a console: “Runtime error 243 occurred at 1c:2363”, where 1c is the XPC and 2363 is the address. How can i find the responsible function in the memory map file?
