Segmentation fault

[mkroening]

When running the rust example on 484a8bd, I get Segmentation fault (core dumped).

This is the first commit with this issue.

How did you run the example?

On current master, i get

…/examples/rust > cargo +nightly run

You should generate symbols with `nm -n $BINARY > tracedir/$BINARY.sym`
INFO: Linux mode is NOT fully supported yet! To get symbols working, you have to
      edit the sid-00.map and merge the section for each binary, so that it only occurs once.
      Needs to contain at least [stack] and the binaries you want symbols of.

Ah, yes. Sorry, I forgot to specify, that you need to change the example's Cargo.toml to actually use the local rftrace crates instead of 0.1.0 from crates.io.
