Segmentation fault in reassembled binary

Another possible bug.

**Issue:**
```
$ ./08e6e84cab2284e35e4808f1891290b0519f1e3f_GlobalDCE1061_12_bin_ref
$ echo $?
0

$ ./08e6e84cab2284e35e4808f1891290b0519f1e3f_GlobalDCE1061_12_bin_mod
Segmentation fault (core dumped)
```

**Build:**
```
$ clang -O2 -fPIC -fPIE -pie 08e6e84cab2284e35e4808f1891290b0519f1e3f_GlobalDCE1061_12.c 08e6e84cab2284e35e4808f1891290b0519f1e3f.ll -o 08e6e84cab2284e35e4808f1891290b0519f1e3f_GlobalDCE1061_12_bin_ref

Start by unpacking reproducible.tar.gz and rebuilding the reference binary with the clang commands shown in the issue. Run retrowrite on that binary, build the rewritten assembly, and compare the two executions; done means identifying and correcting the cause of the modified binary's segmentation fault.
