Проблема заключена в том, что в этом месте: PE/src/parse/Import.cpp:32 происходит чтение больше чем размер файла.

Когда идет обработка 0x5 по счету ImportDescriptr-а, то его файловая позиция в 32-й строчке равна 0x3D89 при размере размер 0x914 , что составляет 0x18077 и это больше чем размер файла, который равен 96768 байтам, т.е. 0x17A00.
