Summary:

Mac OS X 10.5.1's TCSH will have segmentation when using utf-8 locale and with .history file contains certain data or certain size. This normally has been considered to be Terminal.app problem because it looks like Terminal.app always refuse to open a new process for a new window.

Step to Reproduce:
The sample .history should be attached with the bug, but also available from the URL in the transcript:
[localhost:~] johndoe% bash
localhost:~ johndoe$ cd
localhost:~ johndoe$ mkdir backup.tcshtest
localhost:~ johndoe$ mv .history .login* .cshrc* .tcsh* backup.tcshtest/
localhost:~ johndoe$ curl http://mjhsieh.googlepages.com/history-crash -o .history
localhost:~ johndoe$ bash -c 'LANG=en_US.UTF-8 tcsh'
Segmentation fault
localhost:~ johndoe$ bash -c 'LANG=C tcsh'
[localhost:~] johndoe%
[localhost:~] johndoe% exit

Expected Results:
No segmentation fault

Actual Results:
Crash.

Regression:
it only occurs when: 1. in utf-8 locale 2. with certain .history file.

[localhost:~] johndoe% tcsh --version
tcsh 6.14.00 (Astron) 2005-03-25 (powerpc-apple-darwin) options wide,nls,dl,al,kan,sm,rh,color,filec
[localhost:~] johndoe% uname -a

Notes:
This issue has been addressed in other OS, https://bugs.launchpad.net/ubuntu/+source/tcsh/+bug/86683 and the solution proposed is to upgrade the tcsh.
