Unhandled Exception thrown parsing files

Open nurajbihari opened this issue 2 years ago • 1 comments

Here are some exceptions that I'm receiving when parsing files. There seems to be mainly two:

  1. Unhandled exception. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.
  2. Unhandled exception. System.OverflowException: Arithmetic operation resulted in an overflow.

This is occurring it both the lecmd and nuget package that was created. The hashes are the files that are causing the exception. eg 0614ed9d8815219f4db92f425062f969b8ea654cf0b2fd08ee5070617bccd430

You can find a few of the files here. The password to the zip archive is "infected". https://drive.google.com/file/d/1oUxBnqZ3QChLYnr-7XxzXB2HbwZR1hTj/view?usp=sharing
