SYMPTOMS

When you use the Microsoft .NET Framework System.Security.Cryptography.RSACryptoServiceProvider class in an application, the GC heap may become corrupted, and the application may quit unexpectedly (crash).

CAUSE

The GC heap becomes corrupted if you call the System.Security.Cryptography.RSACryptoServiceProvider constructor during garbage collection. This call to the constructor involves additional private method calls that are not coded correctly to interact with the garbage collector. This behavior may cause memory corruption.
