Re: 'Select' errors for a deferred class

Hi Eric,

Having done a bootstrap build of 'gec' from the latest git repo today, I
can confirm that the issue below is, or appears to me to be,
outstanding.

I did do some browsing of the code in the tools library, but have not
yet identified how the issue arises or is treated differently by gec vs
EiffelStudio.

I am using the Eiffel 7.0 Vision2 interface and implementation_interface
clusters, with my own implementation cluster, essentially everything
else coming from the current ${GOBO} path ...

I will attempt to create a minimal compilation that demonstrates the
compilation error, possibly while I am in Prague for the TOOLS 2012
conference next week [departing at some unearthly hour tomorrow
morning !].

Cheers,

Howard

Did you manage to understand what the problem was?
What version of EiffelVision2 did you use? I already compiled
classes from EiffelVision2 with Gobo in the past, and never
saw this kind of problem.
