Hunting down application errors coming from csrss.exe

I'm the maintainer of a legacy Delphi application. On machines running this program an Application Error appears sometimes with the caption referring to this Delphi app and a message like the following:


The instruction at '...' referenced memory at '...'. The memory could not be 'read'.

Click on OK to terminate the program.


Task Manager says the process belonging to this message box is csrss.exe. What would be a systematic way to find the root cause of this error?

The problem is, this Delphi program is fairly complex, and the error message appear relatively rarely, so I cannot simply step-through the code and find the part which causes the error. Moreover, the app runs automatically, without user interruption, so I can't ask the user what she does when the message appears. Application and system logs don't indicate any problem. The app does not stop working when the message box is present.

I hope someone has run into such an error message before and was able to solve the problem. Thank you for your help in advance.
