This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.
Comment 13 Pavel Šimerda (pavlix) 2015-03-14 00:22:44 UTC 
While this one's pretty old, I attempted to analyze it and my conclusion is that the crash occurs in the call to gethostbyname2("hhmcefx", AF_INET) which static storage for the result and thus should be generally safe. The program is single threaded so I don't see any reason to introduce an issue.

I would normally switch this bug report to glibc but unfortunately there is no debugging information for the glibc part. In this situation, closing will be the best thing to do for now.

Please reopen if you have more information.
