• unpack DynamicCheckUp compressed file

• make

• optionally run the DynamicCheckUp unit test

  ./DynamicCheckUp ./Dynamic_DCU_UnitTest
  

• optionally run the DynamicCheckUp on every day applications

  ./DynamicCheckUp $(which ls)
  ./DynamicCheckUp $(which glxinfo)
  ./DynamicCheckUp $(which glxgears)
  

• compile the target application with debug symbols (-g)

• run a dynamic check-up on the application

  ./DynamicCheckUp ./MyTargetApplication Parameter_1 Parameter_2 Parameter_3
  

• DynamicCheckUp log will be written to "memory_check_up.txt"

• DCU_THREAD_SAFE
  • Use thread synchronization for memory requests and releases.
• DCU_C_MEMORY_CHECK
  • CheckUp C memory functions (malloc, calloc, realloc, free)
  • WARNING : C memory check-up is not accurate, and problems may be incorrectly reported
• DCU_ECHO
  • Echo information while running application (only useful for static linking debug)
• DCU_ABORT_ON_RELEASE_NOT_REQUESTED_MEMORY
  • Aborts application and reporst when a memory release (free, delete) occurs on not requested memory (new, malloc, calloc)
• DDCU_ABORT_ON_MEMORY_OVERWRITE
  • Aborts application and reports when a memory overwrite occurs

• xx.12.08 - Main code development.
• 15.01.09 - Main leak detection code.
• 20.01.09 - Locate several leaks on the same allocation frame.
  • Parse DCU_OUTPUT_FILE and resolve hex addresses to function names, filenames and lines.
• 21.01.09 - DCU_FreeNullType problem detection implementation.
  • DCU_RequestZeroMemoryType problem detection implementation.
• 26.01.09 - DCU_MismatchOperationType problem detection implementation.
• 27.01.09 - DCU_ReleaseUnallocatedType problem detection implementation.
  • Memory Overwrite Protection implementation.
• 28.10.09 - Major revision on system. Use of public domain dlmalloc allocator as underlying memory allocator
  • __builtin_return_address was replaced with backtrace :)
  • The first call to backtrace calls malloc, so we must call it explicity on DCU_initialize()
  • Support for x64 systems.
  • added memalign (but it is not used by the memory management system)
