We use SolFs v3.2.0.95 in our product. We have a mini crash dump from Windows Error Reporting and the crash is in TStorageObjectUpdateDataIndexPages when writing to a file. Crash happens when updating an index page. TStorageGetPage is called to get the index page which for some reason fails and the returned pointer is dereferenced without checking for NULL. In mini dump there is limited information so we cannot see what state the storage objects are in. I wanted to check if it is expected that sometimes TStorageGetPage can fail here to get a page or does this failure indicate some other problem?

Most likely the storage was corrupted for whatever reason before the operation. And the crash was just a consequence.

BTW version 3.2 is 6-year-old and there were numerous improvements made in versions 4 and 5.


Sincerely yours
