Nevermind, I was told by someone from #bash in IRC that this issue has been
raised multiple times:
* http://lists.gnu.org/archive/html/bug-bash/2014-01/msg00126.html
* http://lists.gnu.org/archive/html/bug-bash/2011-05/msg00020.html
* http://lists.gnu.org/archive/html/bug-bash/2013-05/msg3.htm
I noticed that bash from the devel branch was taking too much time to start
when invoked as an interactive shell. I happen to have bash-completion
installed.
See this:
| dualbus@hp:~$ for sh in /bin/bash /tmp/bash/devel-O2/bin/bash; do time "$sh"
-i <<< ''; done
| dualbus@hp:~$
| dualbus@hp:~$
