[lldb-dev] suspect bug: lldb segfault when redirecting `--version` output

[Alexander Samoilov]

Hi All,

Stumbled upon the following behavior:

```sh
$ /usr/bin/lldb --version
lldb version 3.6.0 ( revision )
```
ok, but
```
/usr/bin/lldb --version  >& LLDB.VERS
Segmentation fault (core dumped)
```
Suspect a bug, debugged it a bit, failed in `wcscmp ()`
More details are here:

Thanks!
Alexander
