[BUG] UE 4.15 - MAP STRING/STRING in function local variable make editor to crash

  • Create new project
  • Create a function anywhere you want (level blueprint for example)
  • Create a String/String map local variable inside this function
  • Make default value inside this variable
  • Don’t bother to assign the variable
  • Call the function in runtime

---------> Editor crash…

If the variable is empty, everything is allright.
If you create a map STRING/INT for example and put default value, the function doesn’t want to compile…

What the hell they doing with map variable?
