[Mono-devel-list] Exception at System.Type.IsAssignableFrom when using AssemblyBuilderAccess.Save

[Kamil Skalski]

Hi!

We have encountered a little bug in mono when using 
System.Reflection.Emit.AssemblyBuilder with AssemblyBuilderAccess.Save 
attribute given. 
When IsAssignableFrom method of System.Type is called for mscorlib's 
System.IComparable against currently builded type, the exception occurs in 
runtime:

Object reference not set to an instance of an object
in <0xc73f8a1c> (wrapper managed-to-native) 
System.Type:type_is_assignable_from (System.Type,System.Type)
in <0x00004> (wrapper managed-to-native) System.Type:type_is_assignable_from 
(System.Type,System.Type)
in <0x0003a> System.Type:IsAssignableFrom (System.Type)

I don't have yet the simple testcase - it is occuring while compiling program 
with Nemerle compiler and separting the issue will probably take some more 
time. Does someone know what it might be? Otherwise I will try to create the 
bugreport with testcase.
