[BUG] Segmentation fault in reassembled SPEC2006 binaries with asan tool

**Describe the bug**
When SPEC2006 benchmarks are rewritten using Retrowrite ASAN tool, and recompiled and run, I am getting "Segmentation Fault(core dumped)" .

**Describe how to reproduce the bug**
Step 1) for compiling PIE to be used as input to retrowrite ASAN tool
platform: x86-64
compiler: gcc 5.5
compiler flags: -O2 -PIE
benchmarks: SPEC2006 benchmarks: gcc, bzip2, ....

Step 2)
platform: x86-64

```
python3 -m rwtools.asan.asantool ./bzip2_base.gcc ./bzip2_base.gcc-asan
sed -i 's/asan_init_v4/asan_init/g' bzip2_base.gcc-asan.s
```

Step 3) For compiling -asan.s file generated by retrowrite
platform: x86-64
compiler: gcc 5.5
compiler flags: -O2
benchmarks: SPEC2006 benchmarks: gcc, bzip2, ....
Compile SPEC :
`gcc -g -o bzip2_base.gcc-asan -O2 bzip2_base.gcc-asan.s -pie -lasan -lm`

Start by reproducing the reported flow with rwtools.asan.asantool on the SPEC2006 bzip2 binary, then compile the generated bzip2_base.gcc-asan.s using the provided gcc command. Inspect where the rewritten binary fails at runtime and compare the generated assembly with the original execution path. Done means the reassembled ASAN-instrumented benchmark runs without a segmentation fault.
