Issue:
The default value of stack size in "limit -h" in tcsh has changed to "unlimited" in kernel-2.6.18-92.el5, whereas previous kernel versions have some value. Is this a bug or a specification change?
Resolution:

This is a specification change from kernel-2.6.18-92.el5(Red Hat Enterprise Linux 5.2). x86 and x86_64 have hard stack limits by default, ia64 was an alignment with them, and is not a bug but a specification change.
