Output of dnet for postinc_2.d

Description of Problem:


I used simple D2 program, to test it:

// postinc_2.d
void main() {              
   for (int i; i != 3; i++)
   {                       
   }     
}

Compiled it using dnet compiler to il (attached), and then used ilasm2 to
compile it to exe.

$ ilasm2 postinc_2.d               # works
$ ilasm2 /debug postinc_2.d        # crash

Assembling 'postinc_2.il' , no listing file, to exe --> 'postinc_2.exe'


Unhandled Exception: System.IndexOutOfRangeException: Array index is out of
range.
  at Mono.ILASM.MethodDef.GetLocalVars () [0x00000] in <filename unknown>:0 
  at Mono.ILASM.SourceMethod.Write
(Mono.CompilerServices.SymbolWriter.MonoSymbolWriter writer) [0x00000] in
<filename unknown>:0

  at Mono.ILASM.CodeGen.Write () [0x00000] in <filename unknown>:0 
  at Mono.ILASM.Driver+DriverMain.Run () [0x00000] in <filename unknown>:0 



Even if dnet compiler is producing bogus il file, ilasm2 should not crash.


How often does this happen? 
Always

Additional Information:
Using Debian sid.

Both mono 2.4.0 and 2.6.3 have this behaviour.
