Created an attachment (id=406651)
--> (http://bugzilla.novell.com/attachment.cgi?id=406651)
test code to reproduce the problem.
Description of Problem:
fsintellisense sample in F# cross platform package doesn't work.
Following the instruction written in http://bit.ly/fncC3g, it stops working
after typing "tip 0 6".
Invoke()-ing UntypedParse() at FSharpCompiler.fs:49 raised exception.
Actually, the sample code does not raise exception, as its exception handling
is not good.
Attached is the shorten code to reproduce the problem, which has to be compiled
with FSharpCompier.fs.
Reproducibility for various environment is written below.
* Mac OS X(10.6.5), Mono-2.8.1 ... Exception
* Mac OS X(10.6.5), Mono-trunk(2.9) ... Exception
* Ubuntu(x64) 10.10, Mono-2.6.7 ... Success
* Ubuntu(x64) 10.10, Mono-2.8.1 ... Success
* Windows 7(32bit), .NET framework ... Success
Steps to reproduce the problem:
1. Install Mono-2.8.1 and F# cross-platform package
(http://fsxplat.codeplex.com/releases/view/55463)
2. Clone fsxplat sample codes.
$ hg clone https://hg01.codeplex.com/fsxplat
3. Go to the fsintellisense sample directory.
$ cd fsxplat/samples/compiler/fsintellisense
4. Copy attached file to the directory.
5. Compile it with FSharpCompiler.fs which comes with fsintellisense sample.
$ fsharpc FSharpCompiler.fs testProgram2.fs
6. Run it.
$ mono testProgram2.exe
Actual Results:
Following exception is reported.

Expected Results:
No exception is reported. Following is the result of Ubuntu(x64) 10.10 and
Mono-2.8.1

----------------------------------------------------------------------------
How often does this happen?
Reproducible.
Additional Information:
I think this problem is somewhat important, because same Reflection code is
used for F# plugin for MonoDevelop.
Also tried Mono-trunk(as of Dec.30th JST) on OS X. It also failed.
(I don't know following result is relevant or not, as this is my first build of
Mono-trunk on OS X)
