"Abort trap: 6" crash on options parsing / osx 10.11

[ofZach]

When I use Poco::Util::Option I am getting a crash on 10.11 (but I think not on other versions of osx) when I supply a command line option (but no crash if there is no option)

for example, with the pkill example, I see this backtrace:

when I run: pkill -h

Cannot reproduce. Also, there would be no explanation why it should suddenly stop working. Most likely there is some kind of build issue on your side. Try cleanly rebuilding everything.
