Salut Adrian,

when I try to use this SUB

Sub ToXML(args As String[])
  
  Dim xml As New XmlWriter
  Dim item As Object
  'xml.Open(args[0] & ".xml",TRUE,"utf-8")
  xml.Open(modPath.FullPath(args[0]), True, "utf-8")
  xml.StartElement("P")
  xml.Attribute("DBReport.Version", 3)
  ToolBox.ToXML(xml, "*")
  For Each item In ide.GeneralParams
    item.ToXML(xml)
  Next
  Layout.ToXML(xml)
  xml.EndElement()  ' ("P")
  xml.EndDocument()
  $fname = modPath.RelativePath(args[0])
  layout.Modified = 0
  If $QuitOnSave Then ide.Push("REPORT.QUIT")
  
End


on line 

xml.Attribute("DBReport.Version", 3) 

the following error raise into the IDE console and then hangs

*** glibc detected *** DBReportDesigner3: free(): invalid pointer:
0x0961af44 ***

if I comment out that line, my project stops with a signal 6


I get that :
*** glibc detected *** DBReportDesigner3: munmap_chunk(): invalid
pointer: 0x08f286ac ***
