This is the sample code in the book: PlantUML_Language_Reference_Guide.pdf

@startuml

You can try to turn arround this issue by simplifing your diagram.

In V7986, this is not crashing anymore.

However, the diagrams (in ASCII mode) are not splitted : this is quite annoying to implement, so please tell us if this is really mandatory for you.

Thanks,

For me it is not 100% necessary but it would be more consistent with the other output formats. Currently e.g. when having 2 newpage commands 3 files are generated, all 3 with the same full content. I think that either there should be 3 separate files with the different parts or there should only be 1 file (and this should also be mentioned in the manual / help.
