Max allowed text length in a text box within Report section

I have a text box in a report section. This text box is sourced from some text variable (Length=1024). When a report tries to display this section Navision crashes. The max allowed length not leading to a system crash for this variable is 404. Is it a normal behavior?

Ok, here is what I do:

1. Create a new report with a Customer dataitem (for example).
2. Fill in the code:

Customer - OnAfterGetRecord()
[
 FOR I:=1 TO 405 DO //  I is a Local integer variable
  TextVar[I]:='A';  // TextVar is a Global TEXT (Length=1024) variable
]

3. Create a section with a Text Box sourced to a TextVar variable (SourceExpr=TextVar)
4. Compile, Save and Run a report.
5. Enjoy your Navision crash (EventType: navisioninternalerror P1: navision P2: 03.70.01.16172 P3: 8 P4: 24)

This issue was reproduced on different clients, different reports, different databases with Navision 3.70A and 3.70B SQL and single user versions.

Any suggestions would be appreciated.

I guess it is:
24-8 Internal Errors #Err_MT_RecordTooLong (Module_MT,8 )

But what does it mean?

Have anyone else experienced such a report section TEXT length issue?

Thanks for your help, ara3n.
