What steps will reproduce the problem? 1. This is an intermittent bug. I am not completely sure what conditions will reproduce it repeatably; however, it only occurs after postweaving. I am going to attempt to look into it.

The issue produces a System.InvalidProgramException. On runing peverify.exe against the assembly, I have so far seen these two errors:

Branch out of the method
jmp / exception into the middle of an instruction

What version of the product are you using? On what operating system?

120, Windows XP, .NET 3.5, VS 2008 C#

Please provide any additional information below.

This may be too much detail, but I tried posting it elsewhere, however, it did not successfully post possibly because of its size.

I'm posting the peverify errors and the ILDasm for the particular methods in this message.

PEVerify output: UIManager::ShowPage][offset 0x000001E6] Branch out of the method.

Here is what I think is the offending line: IL_01e6: brtrue.s IL_024e

I have virtually no IL experience, however, it looks like the "label" IL_024e does reference a branch outside of the method.

Next Error: UIManager::MediaFileAdded][offset 0x000001E9] Branch out of the method.

I figured out how to repeatedly reproduce this problem, but I am not yet sure what to do about it.

To reproduce it, put this function into a C# class and compile it, then run the postweaver on it:

public void FuncTest(String s) { if (!String.IsNullOrEmpty(s)) { string testString = s; } }

The IL code that comes out of this looks something like this:

IL_01cc: ldnull IL_01cd: ceq IL_01cf: stloc.1 IL_01d0: ldloc.1 IL_01d1: brtrue.s IL_0191

In a non-woven assembly, brtrue.s is relative branch to the last instruction in the function - a "ret"

In a woven assembly, the relative location is no longer valid because of the "epilog" that is added to the function by the postweaver. It seems that the same construct causes both peverify errors, i.e., "Branch out of the method", and "jmp / exception into the middle of an instruction". My guess is that somehow, the relative branch needs to be to the beginning of the epilog. How to do this, I have not yet figured out.

The AspectWeaver will now modify all Ret instructions inside a method body to jump to a dummy 'Ret' instruction label to signal the end of the method. Bug Fixed.
