Ciao Dario
Pharo 1.4 is at least 3 years old so you should really consider to migrate.
You **cannot** imagine how many improvements we did since then.

Ciao,
I wrok into Pharo Pharo1.4 Latest update: #14445
I have a strange behavior relative to hash and = methods
into one class.
Sometimes when i do the code aBag occurrencesOf: anItem the
system answer 0 but into the bag there's the relative anItem instance.
The problem is generated when in the anItem class definitions method,
i do reference to a instance variable ( consumer ) setting to a
Symbol.
The hash method is:
hash
^item hash
bitXor:( opzioniVoce hash
bitXor:( referenceTime hash
bitXor:( consumer hash
bitXor:( newEntry hash ))))
The = method is:
= anItem
| rslPrz |
anItem ifNil:[^false].
self class = anItem class ifFalse:[ ^false].
rslPrz:= ( item = anItem item
and:[ opzioniVoce = anItem opzioniVoce
and:[ referenceTime = anItem
referenceTime
and:[ consumer
= anItem consumer
and:[
newEntry = anItem newEntry ]]]]).
^ rslPrz
If i remove the consumer instance reference in the two methods all work
fine.
any ideas about it ?
Thanks,
Dario
