[Mono-dev] Crash on Android when trying to execute dynamic code

I've been trying to port the F# Interactive to run directly on android.
I have a package that loads under android and can generate IL but it fails
with an assertion (presumable in the JIT compiler, but I'm not 100% sure).
The app source can be found here:
https://github.com/robertpi/fsiandroid
You need the latest Xamarian Studio updates from beta channel to build and
run it. You always need a new line the program you enter, or the compiler
refuses to run (not sure why). I've been testing with the following snippet:
"let x = ""
"
I seem to have enter the program twice before it compiles and executes, not
sure why, working on finding this out myself.
I tried grab the IL code generated, but for some reason it always gets
truncated in the log.
The program fails with the following stack trace:

I've tried checking out mini-arm.c:3599, but it currently seems to be a
comment. I'm not sure how you find the source for the version of Mono that
Android is running on. Any help fixing this greatly appreciated.
Many thanks,
Robert
