    Description

      Executables compressed with mpress.exe (used by SumatraPDF) are not mapped correctly by ROS.
      The attached testcase runs fine uncompressed, and crashes (due to missing kernel32 import - CORE-6957) in the compressed version.
      There are two sections, one starting at 401000 with size 4000, one starting at 405000 with size 320.
      ROS maps the headers correctly, then has a gap from 401000 to 405000, and maps a zero page at 405000.
