Comment 6 for bug 1294958

libgcc1 1:4.9-20140222-0ubuntu1 is installed on your system. In fact it could not be uninstalled since it's in libs/required and f.e apt depends on it. So I doubt that php5-cli I at fault and I am reassigning this to libc to check what might have caused this.

If anything it went through libmysqlclient.so.18 before crashing...
