libpdfium.so GC error

Version

pdftext==0.6.3
pypdfium2==4.30.0

Problem

The Python garbage collector is collecting TextPage objects while PDFium internally cleans up CPDF_TextPage resources, both accessing the same memory region and leading to a race condition.

Thought

https://github.com/datalab-to/pdftext/blob/master/pdftext/pdf/pages.py#L277-L289

Can we manually call textpage.close() to release resources after using the TextPage object?

Can we upgrade pypdfium2 to 4.30.1?

4.30.1 Changelog

PdfPage.get_objects(): Don't register pageobjects as children, because they don't need to be closed by the caller when part of a page. This avoids excessive caching of weakrefs that are not cleaned up with the object they refer to.
