Hi Hilaire,
I think this is the same bug as
https://pharo.fogbugz.com/f/cases/13854/frameSize-calculated-wrongly-for-lineSegmentsDo
this is fixed in pharo4.0 and pharo5.0 but not in pharo3.0
I modified the changeset for pharo4.0 to make it loadable in pharo3.0
But I did not looked further on the code changes, maybe it won't fully work.
Find attached the changeset. You have to switch compiler class before and
after loading this.
SmalltalkImage compilerClass: Compiler.
'opal_drgeo.cs' asFileReference fileIn.
SmalltalkImage compilerClass: OpalCompiler.

IRClosureStackCount is used to distinguish between a stack
in the method scope and a stack within a closure block. The
closure stack size is independent of the number of tempvars from the compiled method, therefore that number is subtracted
from this stack size length.!
