System.ExecutionEngineException for certificate object creationI am using the SecureBlackBox class to create a new X509 certificate. SBX509.TElX509Certificate certUsr = new SBX509.TElX509Certificate(); certUser.LoadFromBuffer(certData); This works fine in some areas of my code but all of a sudden, a certain part of my code is throwing a System.ExecutionEngineException on that line. I debugged it and went over my code line by line and this is the exception info. I have no idea what to do. Funny thing is that my try-catch doesn't catch this. Any suggestions???? Cheers.

managed heap with some interop or p/invoke that went wrong. In any event, you would need to take this to them first as MS won't touch it directly since it happened in a third party component (I don't think). Joe K.

I don't think its a SecureBlackBox issue because I am using the very same call throughout my application in different functions. Its only this specific call to object creation that is throwing the exception. If I comment it out, no exception is thrown. The application is a Client/Server chat program and the exception is being thrown in one chat client. I used the very same object creation call in the server right before I send the data to see if its an issue with SecureBlackBox and it worked fine. I don't think the CLR is corrupted because it runs all the application I have as normal. 2 follow up questions:- -A friend of mine suggested that I compile the code above for release instead of debug as I am doing now because the CLR for release is "different" to the debug CLR. Is this true? Is there "really" a different CLR for release and debug? -Another friend suggested I look at the stack size to see if there were any issues in there. Can the ExecutionEngineException be thrown because of Stack "miscalculations"? I will try this on another machine to see if it still throws the exception. I'll post a bit later with the results of that. Thanks for your replies. Sushant Bhatia I'm not sure how you can conclude that the vendor component is not at fault
here just because it works some of the time. These types of errors tend to be hard to track down and there might be a combination of symptoms that causes the problem. Changing to a release build might help with the problem (l've seen that before personally), but that does not bode well that the problem is solved. Still, it is worth a shot. If stack SIZE was an issue, you would probably have gotten a StackOverflowException like you get from infinite recursion and such. I'm still betting on some kind of corruption that happened due to some unmanaged code doing something to memory that it should not have. The classic way to debug this would be to use a lower level debugger like windbg with the SOS extension loaded, but there is steep learning curve there if you are not already skilled. I can't be of any assistance with that. You might consider posting on the dotnet.framework.clr newsgroup to see if they have any suggestions as a lot of the more hard core CLR guys hang out there. Best of luck, Joe K.

For some reason, when the same code at home (without recompiling) I get errors for the initialization. I posted the errors caught at http://temphome.mine.nu/blogs/ankh_morporks_finest_coder_ii/archive/2005/05/03/208.aspx Its wierd that my school machine thrown the ExecutionEngineException but my home machine is able to catch the specific cause. I still have no idea what the exception actually "means". I know the cctor() function is a class constructor function but why should a constructor which takes no parameters throw a TypeInitializationException->NullReferenceException unless something internal was being initalized. And why won't this error be thrown everytime the constructor is called? Have you reverse compiled it with reflector to see what is in the cctor? It
might be unmanaged code which you might not be able to see, but perhaps you can get more info. My guess is that it is still memory corruption do to some bad pointer stuff. NullReferenceExceptions in unmanaged code sometimes indicate other types of pointer problems than a simple null reference. I'd go to the vendor, especially if you can create a repro. Sending them a crash dump of the process should help. Joe K.
