I'm using 1.0.92 x86(.net4) version. on Win8.1 x64 OS Visual Studio v2013

I don't know what's going on, When I get object

Person = ctx.Persons.ToList();

It will throw FatalExecutionEngineError exception, and I can't get any details about this exception. Is there any way fix it please?
Thank you.

Have you tried using a more recent version (e.g.

Also, do you have all the Windows updates installed?

I just try 1.0.97 x86 .ner4 version binary and test. same result.
I also check my win8.1 update, there is some updates but that's just a option update, not a important update(it always auto install the important update every monthes). I don't know which update do you mean.

I have never seen this exception happen due to System.Data.SQLite.  Perhaps it
would be prudent to run diagnostics on your RAM and/or file system?  Search the
Internet for "Windows Memory Diagnostics" and/or "chkdsk".

I think that's not a memory problem. because I already test my memory few months ago, it's fine. and I open onother old project, it's all fine(it use slite too), no this problem.
Now I still not get it, what's happening in my this project......

It would be very helpful if you could provide the schema of the database
involved as well as an example project that demonstrates the issue.

I use win8.1 memory check feature but there is all fine. I also install or win8.1 optinal updates, But the result same.

I can give you output the .sql file. But because the project is own my company, it's very private, I can only send it to your email. Tell me your email address please.

Create another project from zero for example, but now no exception, give me a little time for test it again please.

I finally find the source, There is some place access some dll, there is no any exception outside, but I still think maybe there is some place something happening. Because after I remove that place no exception from sqlite anymore. I still not understand why , I'll continue check tomorrow.

The dll I think it's access a device which is connect with the PC. the access device code writted by c language. If it affecting the sqlite, I'm very impressed.
