Dear SCO Customer, Support Level Supplement (SLS) ptf4067b, the SCO UnixWare 2.1.3 libprof Supplement, addresses all the problems listed below. SLS ptf4067a addressed these issues: 1. fprof start state does not work correctly, specifically the options -m (mark) -o (on) -O (off). 2. fprof gets a segmentation violation error. 3. time start is erratic. 4. The count command doesn't work per the manual page. 5. Certain behavior of marks is not documented. 6. Documentation describes arguments to the count and seek_mark commands that are either not parsed or not supported. SLS ptf4067b additionally addresses this issue: 7. SLS ptf4067a changed permissions of /usr/ccs/lib/libfprof.so.1 from 0755 to 0444. Removing ptf4067a kept permissions set at 0444. Now, removing ptf4067b restores the original permissions of the library to 0755.
