      Description

      MallocScribble is a debugging feature on Mac, if this environment variable is set, allocated and freed memory blocks are scribbled with known patterns to make debugging memory issues easier.

      When starting the debugger from Qt Creator while this variable is set for the program to debug, the debug process terminates with

      STARTING LLDB -i /Users/Shared/qt/creator/3.0/5-release-64/bin/Qt Creator.app/Contents/Resources/debugger/lldbbridge.py /Applications/Xcode.app/Contents/Developer/usr/bin/lldb
      eERROR: python(48043,0x7fff74a28310) malloc: enabling scribbling to detect mods to free blocks
      dHANDLE LLDB ERROR
