Abstract
A method, system, or apparatus to debug software that is reorganized in memory is presented. A post-mortem debugging session is established by loading an executable code component corresponding to a packed binary file into memory. A randomly reorganized layout of the machine code corresponding to the blocks of the original source code is generated based on a transformation defined in a function randomization library corresponding to the blocks of original source code. A core dump file corresponding to the crash event associated with the executing of the executable code component and a debug data file that includes symbol table information to debug the blocks of the original source code are received. An updated debug data file is generated that includes symbol table information corresponding to the randomly reorganized layout. A debugger program is called with the executable code component, the core dump file, and the updated debug data file.
