- Microsoft .NET Framework 1.1 Service Pack 1
SYMPTOMS
When a Microsoft .NET Framework 1.1 application calls a function that contains more than eight hierarchical nested objects, the common language runtime (CLR) may fail, and you may receive an "Access Violation C0000005" error message during garbage collection. This behavior indicates that the managed heap is corrupted. Typically, this problem occurs when the PInvoke method is used incorrectly. Additionally, this problem occurs in a heavy load environment.
CAUSE
This problem occurs because a value in the register is changed but cannot be restored when the .NET Framework 1.1 application calls a function that contains very complex hierarchical nested objects. The corruption is caused by an error in the just-in-time (JIT) complier. The code that the JIT compiler generates does not safeguard the register when the register is not changed.

WORKAROUND
To work around this problem, use an intermediate variable instead of complex nested objects.
For example, change code example A to code example B as follows:
Code example A
ObjA.ObjB.ObjC.ObjD.ObjE.ObjF.ObjG.ObjH.ObjI.MyMethod();
Code example B
ObjFType TempObjF = ObjA.ObjB.ObjC.ObjD.ObjE.ObjF; TempObjF.ObjG.ObjH.ObjI.MyMethod();
STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section. This problem was first corrected in Windows Server 2003 Service Pack 2.
