term freezes when running any command using /bin/bash

[Matthew Kennedy]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

This problem is applicable to the following operating systems: Gentoo
GNU/Linux, Debian GNU/Linux, and HPUX 11. It might be applicable to
other systems, however these are the only systems I've verified it on.

The bug is exercised when you run /bin/bash as the shell. To reproduce
the bug:

  M-x term RET /bin/bash RET

Then in the term buffer, type "ls". This should freeze the buffer.
