Memory leak in createEnumeration

[Jan Rheinländer]

Hi,

there seems to be a memory leak in
XEnumerationAccess::createEnumeration(). When I run the following BASIC
code on a Writer document, I can watch the memory usage go up:

Sub Main
    for i = 1 to 100000
        text = ThisComponent.getText()
       
        paragraphs = text.createEnumeration()
       
        while (paragraphs.hasMoreElements())
            paragraph = paragraphs.nextElement()
           
            parenum = paragraph.createEnumeration()
        wend
    next
End Sub

I discovered the problem first in a C++ Extension where it seems to be a
lot worse (a few hundred iterations are enough). But it also seems to
depend on how many paragraphs your document has. A large document will
fill memory faster than a small document.
