I'm using 2.4RC2 with no issues in VS2013, I suspect your project is loading an old version of vld_x86.dll from somewhere else.
Double check your Debug output to see where the vld_x86.dll is actually being loaded from, should be loaded from here:
C:\Program Files (x86)\Visual Leak Detector\bin\Win32\vld_x86.dll'
