Julia crashes when importing yaml file

[albop]

The steps to reproduce are easy:

- julia
- Pkg.add("YAML")
- Pkg.test('YAML')

The result is :

```
signal (11): Segmentation fault
parse_stream_start at /home/pablo/.julia/v0.4/YAML/src/parser.jl:124
forward! at /home/pablo/.julia/v0.4/YAML/src/parser.jl:66
==================================================================================================[ ERROR: YAML ]==================================================================================================

failed process: Process(`/usr/bin/julia --check-bounds=yes --code-coverage=none --color=yes /home/pablo/.julia/v0.4/YAML/test/runtests.jl`, ProcessSignaled(11)) [0]

===================================================================================================================================================================================================================
ERROR: YAML had test errors
 in test at ./pkg/entry.jl:803
 in anonymous at ./pkg/dir.jl:31
 in cd at ./file.jl:22
```

There is also a segmentation fault when trying to import a single yaml file ( in julia, `YAML.load_file(...)`)

I am reporting the bug here, since albeit, it depends on the third party yaml library, the bug doesn't happen using generic linux binaries distributed on julia's website or with a freshly compiled version of julia.

Operating system is ubuntu 16.04.

Julia version is 0.4.3.

```
sudo apt-cache policy julia
[sudo] password for pablo:
julia:
  Installed: 0.4.3-4
  Candidate: 0.4.3-4
  Version table:
 *** 0.4.3-4 500
        500 http://gb.archive.ubuntu.com/ubuntu xenial/universe amd64 Packages
        100 /var/lib/dpkg/status
```

Seems to be fixed in version 0.4.5 coming to Xenial shortly.
Which upstream versions did you test?

Upstream (the binaries) was 0.4.5.
