When I repeats opening different PDF files, it occassionally crashes as follow:

12-15 12:33:45.088 11385-11929/hk.hku.versitech.eform A/libc﹕ invalid address or address of corrupt block 0x7988cd90 passed to dlfree
12-15 12:33:45.088 11385-11929/hk.hku.versitech.eform A/libc﹕ Fatal signal 11 (SIGSEGV) at 0xdeadbaad (code=1), thread 11929 (Thread-3847)

For every time opening a new PDF file, I invoked
pdfReader.PDFClose()
pdfReader = null
and then create a new PDFReader object to open

attached core dump (crash.txt)
Any way to troubleshoot for the problem?

I'm not using the demo, but using my own activity to open PDF file.
I created a new PDFReader instance and opened a new PDF file immediately after calling pdfReader.PDFClose();
would that be the cause?

what is the codes to open and close?
includ thumb view or other attach the Document object.
mostly, it caused by Invoke Page.Close() after Doument.Close().

Here's the relevant code attached.
When trying to open a file, MyActivity.loadFormAsync(path) will be called.
