[Bug translator/4915] Incorrect code for accessing function argument

["wcohen at redhat dot com" <sourceware-bugzilla at sourceware dot org>]

------- Additional Comments From wcohen at redhat dot com  2007-08-13 14:26 -------
Isn't 2.6.9-55.ELsmp an older kernel? Current RHEL4 is 2.6.9-55.0.2.EL. Does the
debug information for the sys_open function look correct for that kernel?

Looking through the RHEL4 system output for -vvvv see the follow output related
to the generation of the probe points for the 2.6.23-rc2 kernel built with the
RHEL 4 gcc (gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)):
