[Soot-list] New variables added to chain overlap the original ones

[Cristina Ilie]

Hello,

My tool which uses soot introduces sometimes new definitions of new variables in the derivLocalsChain. The problem 

is that some new variables overlap with the existing ones. This occurs when I output directly bytecode...

For example here [1] the IntLinkedStack object overlap on the fifth position with another DerivType object which was in
the original code (actually the DerivType was a double but it existed in the original code! I only change the type to
double and float - doesn't matter this idea...I just exapained).

The new object introduced by me is an IntLinkedStack object and I add it through "derivLocalsChain.add(intStackLocal);" 

where intStackLocal is a JimpleLocal.

I tried also to build the initalization stmt by adding the <init> method (I loaded the  IntLinkedStack class) and 

after this the SpecialInvoke stmt. But the result is the same... How to avoid this overlapping of variables?

[1]9  new IntLinkedStack [46]
     12  dup
     13  invokespecial IntLinkedStack() [42]
     16  astore 5
     18  new DerivType [26]
     21  dup
     22  invokespecial DerivType() [3]
     25  astore 5
