  Is alloca (in "virtualMachine") used only to get some memory that is 
freed automatically on function exit ? or to get memory only from the 
stack ? 

  can someone please explain the need for this call ?

  can alloca be replaced by malloc (& free before function exit). If not, 
can something else be used instead of it to achieve the same effect ?
