First of all I am relatively new to .NET, so bear with me.

I am facing a strange problem related to .Net JIT. Here's the problem:

I have written a .NET method(method-1) that calls into a COM+
component. When I call the method-1 independently, it works as
expected. Issue is introduced only when method calls are made in a
particular sequence. The exception occurs when the method is called.
Can't even step into the function to check which statement is throwing
the exception.

method-1: function which is failing

method-2: another function that creates the same object that method-1
tries to create.

Sequence of method calls:

method-1... method-2     works fine

method-2...method-1 throws an exception with the following msg:

"Request for the permission of type
System.Security.Permissions.SecurityPermission, mscorlib,
Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
failed."

When I tried to debug the disassembly, and put in the method address in
the memory window, it said that the method has not yet been converted
to native.

The "call " instruction was throwing an exception (don't know how). The
only conclusion I can derive is that JIT is somehow failing.
If any of u have any other conclusion or just a solution without
explanation that will also do :)

Please let me know if any part of the post is not clear.

Thanks in advance.
