        I recently upgrade from bash 2.05b to 3.0, and noticed that for some

it seems that ^Z also does not function.  Has there been any change in this
behavior between these versions?  Is this possibly a portability issue with
IRIX 6.5?  stty is showing the terminal configured properly, but simple tests
like a ls -lR / can not be interrupted with a ^C or backgrounded with a ^Z.
The same environment with bash 2.05b continues to function.  Any advice?

IRIX uses deprecated syntax for `trap' in its startup files.  The
use there ends up setting SIGINT, at least, and possibly SIGTSTP

Apply patch 3 to bash-3.0, which restores enough backwards compatibility
to support this use.
