Good afternoon.
I have ~700,000 objects in a SortedCollection and I am attempting to modify them.
WikitextSAXTemplates templates do:[:t | t resetParameterDictionaries].
"t" in this case invokes this:
resetParameterDictionaries
parameters := SortedCollection sortBlock:[:a :b | a key < b key].
nestedparameters := SortedCollection sortBlock:[:a :b | a key < b key].
nestedparamaterizedtemplates := SortedCollection sortBlock:[:a :b | a key < b key].
nestedsimpletemplates := SortedCollection sortBlock:[:a :b | a key < b key].
I get a segfault:
stack page bytes 8192 available headroom 5576 minimum unused headroom 6032

I checked the SortedCollection containing the objects for nil values with both:
|s|
s := Set new.
self collect:[:each | s add:(each class name)].
s inspect.
and:
self select:[:each | each isNil].
I only got one element in the Set and an empty collection in the isNil test.
I will be trying a different tac by fully initializing those objects as they are created and added to the SortedCollection that holds them.
