[Help-smalltalk] Issue with 'Kernel.ConcatenatedStream' and gst-convert

[Holger Hans Peter Freyther]

Hi Paolo,

I am having a problem with the Kernel.ConcatenatedStream when trying
to convert multiple files to the Squeak/Pharo fileout. I have attached
two simple files and execute the following.

$ gst-convert  -F squeak -f gst -o foo.st LogArea.st Timer.st

The ConcatenatedStream at this point is at the end. 'self stream' is returning
nil at this point so 'end <= startPos' does not appear to trigger but also
adding:

'stream isNil
            ifTrue: [stream := last. adjust := lastStart]'

does not work. Do you have an idea?
