Bug only occurring when compile optimization enabled

Question

I came across a bug in code that is only reproduced when the code is built with optimizations enabled. I\'ve made a console app that replicates the logic for testing (code

This bug seems to have been fixed in .NET 4 (beta 2). Here's the optimized x86 disassembly for the bit nobugz highlighted, above:

                    Console.WriteLine("Post-check Value is: " + value);
00000056  mov         ecx,dword ptr ds:[033C2090h] 
0000005c  mov         edx,dword ptr [ebp-8] 
0000005f  call        65D8FE10

The program also displays the expected output in both optimized and unoptimized modes.
