Eyesee in VW7.6

I've been able to load and run Eyesee in VW 7.5 but not in VW 7.6.  It seems to go into a tight loop a few minutes before crashing with at out of memory error.  Any ideas. Thanks, Lynn

You  could load the StackOverflow package so it breaks rather than runs
out of memory then go down the stack trying to identify the recursion.

good luck

I only have 7.5nc, and I have no idea how to obtain 7.6nc so I cannot  
test this.

On the Cincom site it is said that the current version is 7.6, but I  
can only download 7.5.

So, is 7.6 available as nc as well? If yes how could I download it?


Cheers,
Doru

Howdy,

CodeFoo implements BlockClosure>>cull: with different semantics:

Code Foo:
--------
cull: arguments
   "Evaluates the receiver with as many arguments as requiered."

    self numArgs = 0 ifTrue: [ ^self value ].
    self numArgs = 1 ifTrue: [ ^self value: arguments first ].
   ^self valueWithArguments: (arguments copyFrom: 1 to: self numArgs).


VW 7.6:
-------
cull: anObject
   "If the receiver can handle an argument, evaluate with the argument,
other wise drop the last argument and evaluate as a no arg block."

   ^self numArgs = 0
      ifTrue: [self value]
      ifFalse: [self value: anObject]
----
especially, CodeFoo's cull breaks ifNotNil:, resulting in a nice myriad
of debuggers:

Open a CMD window and start the debug vm from the command prompt
"bin\win\debug\vwntconsole -o10s visual.im". Minimize the CMD window as
it runs--to avoid CMD window refresh costs. I usually set properties on
CMD to buffer 2000 lines and 200 columns. Once you get the crash then
look at the CMD window to see what the VM was doing.

Last week I was tracking down an mmScavenge.c crash this way (using VW
7.5+GBS 7.2.1b1). The precise point of failure was random but the error
was always "thapi com ephemerons immutability debug assert". It was
worked around by increasing memory allocation and growth to accommodate
the new GBS cache design.

re: [ thapi com ephemerons immutability debug assert ]

That's not an error message, that's an identifier of which options are enabled in the particular VM you're using. The error message is "Out of Memory".
