Thanks Igor! :) After trying in in a fresh Pharo3.0 Latest update: #30703 I loaded slice 12674 the test for NB are green and (NBExternalTypeValue ofType: 'NBInt64'). now finally works. With this now "PUnQLite" package can be loaded again in Pharo 3.0 without errors:   Gofer new url: 'http://smalltalkhub.com/mc/MasashiUmezawa/PunQLite/main'; package: 'ConfigurationOfPunQLite'; load. (Smalltalk at: #ConfigurationOfPunQLite) load The examples from https://github.com/mumez/PunQLite work, EXCEPT one: "Import from files" db := PqDatabase open: 'mczCache.db'. (FileSystem workingDirectory / 'package-cache') files do: [:each | (db importAt: each basename fromFile: each pathString) ifTrue: [db commitTransaction]. ]. db keys inspect. db close. which first gives an "PqCursor" error and when run for a second time leads to a hard VM CRASH (on Windows 8). Anyone able to reproduce? Note that one requires UnQLite library to reproduce which is prebuilt here: https://github.com/mumez/PunQLite/tree/master/binary I guess it is somewhere in #importAt:fromFile: which uses memory mapped files...

It works and it's commited.  Thanks! Still there is a problem:
 (NBExternalTypeValue ofType: 'NBInt64'). in a Pharo3.0 Latest update: #30703 (with the fix integrated) throws now an #DNU because the new anonymous subclass of NBExternalTypeValue class does not understand #rebuildFieldAccessors NBExternalTypeValue(class)>>valueType: sends #rebuildFieldAccessors but there is no such method in this hierarchy. But there is NBExternalStructure>>rebuildFieldAccessors and NBExternalTypeValue(class)>>installAccessors. Maybe a leftover from refactoring?   fix in inbox https://pharo.fogbugz.com/f/cases/12674/Fix-NBExternalTypeValue-initialization[https://pharo.fogbugz.com/f/cases/12674/Fix-NBExternalTypeValue-initialization]  Thx Torsten  -- Best regards, Igor Stasenko.
