JIT runner source code

I made a simple JIT runner and now I am trying to feed it with an object file.
When I attempt to run 'main' then it crashes.
Even though it works just fine on Linux (tested on Ubuntu 16.04 32bit).

I attach my simple JIT runner as a main.cpp.
I built it using LLVM 5.0 official prebuilt binaries. I used the following
command:

clang++ `llvm-config --cxxflags` `llvm-config --libs` -lz -lncurses main.cpp -o
jitter

The I just built 'hello world' program:

clang++ -c main.cpp

And fed it to the jitter:

./jitter main.o

This is the trace I obtained from lldb:
