Jb, could you try again using the latest source code (after Jim pushes it) and if it fails send me please full stack trace and complete IL of the offending method?
Sure.
So, after building from source the updated git repo, we have a
different error, but similar error.
I’m simply executing mono ir.exe test.rb, where test.rb only contains
a call to require "mscorlib".
The stacktrace looks like this:

IL_00c5: ret
The issue here is the instruction:
IL_00a2: ret
With is right after an unconditional branch, thus will be executed,
but the IL is still wrong.
