[MinghaoLin2000]

I fuzz the parsePDF functionality using harness PDFParserFuzzingHarness provided in this project. My fuzzer found a stack overflow crash. below is sanitizer's message.

This backtrace message is incomplete due to the screen limitation. I utilize GDB to retrieve the initial parts of backtrace.

It demonstrates that the stack contained so many function frame data that it is overflowed. I have attached my crash sample.
