InvalidOperationException: Stack empty in MethodTrace.TraceArguments called by WinFormsAnalyzer

[LukasTr]

I'm using Confuser.CLI version 1.3.1 on an existing application. This is the assembly-wide configuration:

[assembly:Obfuscation(Exclude =false, Feature = "preset(normal);-ctrl flow;-ref proxy;+rename(mode=reversible,password=12345,flatten=false);")]

This is the output I'm getting:

z:\tools\ConfuserEx\Confuser.CLI.exe application.exe -o=.

Is this a known problem? I will send the exe in a private e-mail.

The issue looks familiar. Could be the one fixed by #127
Could you please try to use the version from the buildserver for the next release?
Find the download here.
