UFFI #rebuildFieldAccessors problem

Hi,

I have the following line in BaselineOfBloc: (postLoadBloc:)

FFIExternalStructure withAllSubclassesDo: #rebuildFieldAccessors.

If I don't rebuild accessors, some offsets are nil in external structures.

However, on Windows 32bit it fails with the following exception:

How to reproduce:

Take Pharo 7 (http://files.pharo.org/get-files/70/pharo.zip)
VM (http://files.pharo.org/get-files/70/pharo-win-stable.zip)
Excecute FFITestArrayStructure rebuildFieldAccessors

Links to Image and VM I took from SmalltalkCI.

The reason I'm posting this is because Bloc Appveyour builds fail and more importantly Stef will give lectures in Prague and they will use Bloc for the semester projects.

Not being able to install Bloc on Windows is not nice :(

We wanted to release alpha version of Bloc and now we can not.

Cheers,

Alex

Juhuuu! it worked with Pharo 6.0 :)

Which means there is a problem with Pharo 7.0.

I will appreciate any help. thanks!

Cheers,

Alex

Re: UFFI #rebuildFieldAccessors problem

I know this problem

annonymousClassCreator

^ String streamContents: [ :stream |

stream

nextPutAll: '(FFITypeArray ofType: #';

print: self objectClass type class;

nextPutAll: ' size: ';

print: self objectClass numberOfElements;

nextPutAll: ')' ]

is where it code goes wrong.

class is...a class.

change to

print: self objectClass type class displayString;
