The new dylan.NET compiler (mentioned above)

THe runtime is telling me that the quantifier is wrong. IN relaity I did not
check anything against the given pattern(checks for 4 numbers separated by
"."). I dod have somethin that conforms to it but the code was made not to
compare it with anything. I think this is an error with the Mono runtime.

Below please find the full content of my console displaying the error. The
source code printed out was the code I was trying to parse. If you need the
original sources of the program contact me on borgdylan at hotmail.com.

#refasm System.Data.dll
#refasm System.Data.DataSetExtensions.dll

class public auto ansi Module1

method public static void main()

Console::WriteLine("Hello World")
var a as integer = 2
var b as integer = 3
var c as char = 'f'
var d as char = ' '
var e as string = "'"
var ans as integer = a + b
var anss as string = ans::ToString()
Console::WriteLine(anss)
//Console::ReadKey()

end method

end class

by using the new dylan.NET compiler. Sources available from me. 
Beforehand a built version of the new dylan.NET compiler is required together
with the Mono runtime 2.6.7. On .NET 3.5 this error is not reproducible as all
works fine.
Actual Results:  
Mono said the followinmg exception happened:
Unhandled Exception: System.ArgumentException: parsing "+^\d{1}.*.\d{1}.*$" -
Ba
d quantifier.
Parameter name: +^\d{1}.*.\d{1}.*$

In .NET 3.5 it does not happen.

Expected Results:  
The exception should not have appeared and the software should have terminated
normally after parsing the whole source file given.

OS: Windows 7 Home Premium
Runtime: Mono 2.6.7 for Windows (did not build myself)
Context: The program that stops is a compiler(attached) designed to run on Mono
