Built with the latest commit.

I believe the offending line is https://github.com/jbevain/cecil/blob/master/Mono.Cecil/AssemblyWriter.cs#L1915 (AssemblyWriter.cs:1915), however I have no clue about the codebase so I don’t really know what this line is supposed to do or how to debug it. Unfortunately I cannot share the assembly, but please tell me if I can do something to assist.
