Follow-up Comment #1, bug #23321 (project grep):

The just attached file shows grep benchmark results.  I got the patterns file
by doing:

cat /etc/logcheck/ignore.d.workstation > /tmp/ignore

The numbers show the startup time for grep with about 2500 regexps read from
a file (logcheck does this every hour) is:
Plain 2.5.3    : 68.0s
CALLOC patch   : 24.2s
int->char patch:  5.8s

Adding 10000 lines of input (my /var/log/daemon.0 log file) doesn't change
the numbers much:
Plain 2.5.3    : 70.4s

Both CALLOC and
int->char patch:  5.7s
