Nicolas, the problem of the TestCoverage is because it uses method wrappers
using "Objects as methods"...this is, using the run:with:with which was not
originally supported in Cog.
However, in this latest VM, Eliot has implement it. So...you need latest
CogVM to run Coverage or any run:with:with.

Binary is http://www.mirandabanda.org/files/Cog/VM/VM.r2313/

you are using THAT VM and have problems ?

The only one I found in Pharo is using the one I already reported in this
email.

Cheers

Mariano
