Sorry for the initial confusion. I got the reason for the error now exactly. I
simply misread the debuggers output.

Situation occurs because of the following behaviour:

- Application calls StgOpenStorage for an file that is already opened.
- In line 6130 *ppstgOpen is set to NULL
- The CreateFileW afterwards fails and the procedure goes into error handling
- *ppstgOpen is not touched any more and points to NULL
- Nevertheless application tries to read data at *ppstgOpen
- So crash there.

My initial fix worked because it allowed a second open to the file and the
pointer got initialized correctly.

Best regards.
