critical bug of memory exhaustion #1115

hello,
I found a critical bug of rapid memory consumption and 100% cpu usage until totally memory exhaustion when using Lief to parse a PE sample(api: lief.parse(...)).
This sample was captured from network traffic, and due to network reason, the sample is incomplete. The sample is assumed to be malicious.
Originally lief 0.8.3-python was used to parse, and I found the newest python version still has the same problem.
Please check whether it is a python version problem or exists in all versions.
