Race conditions can also occur in an object that references a static or unmanaged resource that it then frees in its finalizer. There is a dormant race condition in.net which affects even single threaded code when finalizers are executed. In the above example we will try to ensure that the first thread is the last one that writes value to result variable.

A race condition is an undesirable situation that occurs when a device or system attempts to perform two or more operations at the same time, but because of the nature of the device or system, the operations must be done in the proper sequence to be done correctly. This condition occurs mainly in the logic circuits, distributed and multithreaded software programs.

1 mov eax, dword ptr [sum] 2 inc eax 3 mov dword ptr [sum], eax. The cause is primarily the fact that finalizers are called on a separate thread by.net and may access objects which have already been garbage collected due to aggressive lifetime determination by the.net jit compiler in newer versions.
