Comment 13 Ondrej Oprala 2014-04-01 11:56:34 UTC 
Works for me. Could you please try this with bash in rawhide?

Thank you.
Comment 14 John Schmitt 2014-04-01 16:17:11 UTC 
Installed bash.x86_64 0:4.3.0-1.fc21.

In the time that I ran Fedora 20, I saw this only periodically.  Were you able to find a way to reproduce this reliably?
Comment 15 Ondrej Oprala 2014-07-30 12:17:50 UTC 
No, I've had this command running repeatedly for a few hours, and not a single crash. For now, I'm closing this. If you happen to find a reliable reproducer, feel free to reopen this bugzilla.
