I am observing a crash while calling the CMemFile::Detach() function

The exception with the call stack is as below

kernel32!RaiseException+53 e06d7363 00000001 00000003
msvcrt!_CxxThrowException+36 0103bb7c 7f0f6eac 00d8bf68
mfc42u!AfxThrowFileException+61 00000009 ffffffff 00000000
mfc42u!CMemFile::Seek+42 fffff159 00000001 00000194
mfc42u!CArchive::Flush+26 0103bbf0 7f02d05a 00d32388
mfc42u!CArchive::Close+a

This is occuring after i deserialize an object.

The versionable schema for the object seems to be correct.

Any idea as to wat may cause this problem

    The function AfxThrowFileException has three parameters. The first parameter denotes the cause. In your case this is CFileException::badSeek. This can happen if the CMemFile pointer is changed without notifying the CArchive object. It is better to use the CArchive object to change the file pointer.
