[BUG] VWNC7.4 SmaCC Development Parcel Broken?

There seems to be a bug in the SmaCC parcels delivered with the
VW7.4 distribution. For some methods, the compiled code does not
properly reflect the source.

To reproduce, take a virgin visualnc.im and do:
Load SmaCCDevelopmentUI, SmaCCExampleParsers.
Open SmaCC Parser Generator
Load JavaScanner and JavaParser example definitions
Press "compile LALR"
-> MNU (because scannerDefinition in SmaCCGrammar is nil)

Some searching revealed that the compiled code in
SmaCCScanner>>reduceActionForFile1: and SmaCCEdeg>>to:on: does not match
the source. The compiled code refers to/assigns different
variables than the source does.

Recompiling seems to avoid these problems:

SmaCCScannerParser selectors do: [:sel | SmaCCScannerParser recompile: sel].
SmaCCEdge selectors do: [:sel | SmaCCEdge recompile: sel].


I wonder if my VWNC 7.4 installation is flawed?
[installed from CD, Ubuntu Linux, kernel 2.6.15-12-686, glibc 2.3.6]
The MD5 hash of the SmaCC parcels/visualnc.im are:

John,

as the author of SmaCC, would you mind publishing the current version to
the public store?  I know i have been confused in the past about where
to find the correct version.

FYI: The SmaCC parcels shipped with 7.4.1 are broken, too.
