Tjaks for the response Peter.
The report is in 6 sections, Process Details, Thread Details (0 to 10), Binary images (of many lines), External Modification Summary, Region Summary and Model Details. The only section referring to a crash is Thread Detail 0 and this is included here. Can you make any sense of it ?
