My program crashes when GC perform garbage collect

问题:

My program has a trouble: When GC perform garbage collection,my program always crashes at a function,which is called by main flow several times before

crashing and the first line of this function is GC.Collect().The function main action is sending some bytes to serial port and receiving some bytes from the

same serial port( Both sending and received bytes are below 256 bytes) each time.GC.Collect() calling is for locating the crashing point,it'll be removed in

release edition.

I don't know the exact reason,but I know the exact function where the program crash.So,I have to disable GC or pause GC during the function calling.

How can I do it ?

The kindly response will be appreciated!

sincerely, jizhiguo

回答1:

A crash (not exception) in GC means that unmanaged (ie, C++-CLR, unsafe, or non-.NET) code has corrupted the heap. Check your non-.NET code for potential issues! In particular, are those files in D:\jizg\NSIISys\bin\Debug .NET? If not, they look mighty suspicious to me.

回答2:

Edit: Here's what's going on. You have an object instance of some type that contains unmanaged resources as members. That type has a finalizer (looks like a destructor syntax in C#) that calls Dispose(). Some part of your application relies on the unmanaged resource held by this object - perhaps a handle of type IntPtr. As long as the object stays alive (not collected by GC), Dispose() is never called an the handle remains valid. The problem is due to the program holding on to the raw handle (possibly an IntPtr) without keeping a reference to the managed object holding on to the resource. Without keeping that reference, the object becomes eligible for finalization/collection. Solution: Identify the managed type that manages your resource, and make sure you hold on to a copy of it until you no longer need its resource. When you no longer need the resource, call Dispose() on the managed object yourself to clean things up without needing to call GC.Collect().

回答3:

Just don't do it. Find the problem and fix it rather than just quick-patching it. It will just move somewhere else.

回答4:

There are a couple of messages that seem to be of interest:

WARNING: Unable to verify checksum for C:\WINDOWS\assembly\NativeImages_v2.0.50727_32\mscorlib\6d667f19d687361886990f3ca0f49816\mscorlib.ni.dll

You may want to see why this error comes up, as it may be the problem with the unmanaged API.

Do you have any unmanaged C++ dlls that you wrote?

It seems to have a problem with an image name being possibly corrupt, so you may want to remove code that refers to images and see what happens, and then add in one section of code at a time until you find the block that causes a problem.

回答5:

The defect is caused by stack corruption. Here is a technique that we use in my company to find these issues in release code.

First, download and run appverifier. This is a microsoft tool and only works on windows.

AppVerifier will force your unmanaged code to throw an exeption if there is any pointer problems. However, due to the way .NET initializes, .NET executables will also crash during startup with a false crash. What you need to do , is carefully write a test application in native C which will calls the same unmanaged functions as your .NET code.

Run your code in a debugger. The code will crash with the exact address of the pointer which is causing the problem.

Your code will run very slow. This is because AppVerifier will make windows load a series of tests on your test program.

回答6:

The problem has been resolved!

The actual reason is that an unmanaged function has a wild pointer. I replaced it with a managed version of this function and the problem disappeared.

Thanks all who were concerned about this issue.
