decompilation errors #5

I use ljd-v2.1, decompile several files and work, but at one (so far) appeared such errors. I tried with the other branches, but they did not decompiles files (even those without errors at this decompiles).

 kamil@AsusK53SV ~/ljd-ljv2.1 $ python3 main.py Fillable.luc

Sorry, the control-flow analysis still fails sometimes. I will concentrate on data-flow analysis first. This will take much time. It's possible that I'll have to rewrite it in C++ with a slightly different algo.
