Description:
'sa' gets a floating point exception and drops core after
being recompiled with the shadow password package installed
in the system.
Repeat-By:
Install the shadow password file on the system. Recompile/link
'sa'. Run it and observe the floating point exception.
Fix:
Apply the following patch. The problem was that 'sa' was
redefining the 'bcmp()' routine which 'getpwent()' calls.
