Jason,
I can avoid the ICE by simply not simplifying contexts for all C++ destructors.

+ || (!DECL_VIRTUAL_P (decl) && !DECL_CXX_DESTRUCTOR_P (decl))))
DECL_CONTEXT (decl) = fld_decl_context (DECL_CONTEXT (decl));
}
but it seems to me this is more a workaround - if the destructor is virtual, it
should have VIRTUAL flag set. Or is there any reason we want to handle it
differently then any other normal virutal function in the middle-end?
