[Mono-devel-list] [REGRESSION] Change in mono runtime caused Nemerle do stop bootstraping

[Kamil Skalski]

Hi!

After some binary search work (I need to automatize this...) I found that this 
patch:
http://lists.ximian.com/archives/public/mono-patches/2005-February/055290.html

Caused Nemerle to fail quite fast during bootstrap:

make[3]: Entering directory `/home/users/nemweb/nemerle/ncc'
COMPILE [stage1] Nemerle.dll
 [01;31merror [0m: internal compiler error: got some unknown exception Cannot 
cast from source type to destination type.

in <0x00079> Nemerle.Compiler.TypeBuilder:add_members ()

Func1 f)
in <0x00020> Nemerle.Compiler.TypeBuilder:Iter (Func1 f)

I looked at the code of add_derived_members and there are not explicit casts 
out there. This is probably happening on some of casts performed by compiler, 
which are known to be *valid*. 

Just tell me if I should do some more debugging or file a bug report.
