Comment 1 Mark Riddoch 2014-12-16 13:18:09 UTC
The problem is a buffer overrun in normalise_hostname. Fix underway.
Comment 2 Mark Riddoch 2014-12-16 15:45:59 UTC
Increased buffer size to prevent overrun issue
Comment 3 Timofey Turenko 2014-12-22 15:39:32 UTC
I'm not sure I understand the bug correctly.
But 60-chars long host name does not cause problem (longer is not possible "String 'very_long_hostname_that_can_not_be_resolved_and_it_probably_caused_cra' is too long for host name (should be no longer than 60)"
