Hi.

This is not "Document close" crash..

1. heap corruption detected by dlfree (Fatal signal 6 (SIGABRT))
2. signal 6 (SIGABRT), code -6 (SI_TKILL), fault addr
3. signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00002308
- /data/app-lib/com.access_company.android.docdrive-2/librdpdf.so (Java_com_radaee_pdf_Page_renderToBmp+278)

yes, i think it is render page after Document closed:
correct:
Page page = Document.GetPage(pageno);
page.RenderToBmp();
page.Close();
Document.Close();
incorrect:
Page page = Document.GetPage(pageno);
Document.Close();
page.RenderToBmp();
page.Close();
you can write log in Document.Close() and Page.RenderXXX() and Page.Close(), and PageObjsStart().
and so on.
got sequence of logs.

I understand third crash.

(3. signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 00002308
- /data/app-lib/com.access_company.android.docdrive-2/librdpdf.so (Java_com_radaee_pdf_Page_renderToBmp+278))

So I fixed it like below codes.
if(doc.IsOpen){
  Page page = doc.GetPage(pageno);
  page.ObjsStart();
  .....
}

But I do not understand others.

I think "heap corruption detected by dlfree" is not "Document close" problem...
