I discovered today, (maybe you did to. . . . ) that the stock
egrep on ultrix 3.1 has a small (256??) limit on it's pattern buffer.
Normally this is not a huge problem, but today, calendar generated
388 characters of patterns and egrep managed to stomp on itself in
a way which caused it to use memory until it exhausted itself.
Hopefully no one has egrep running in some setuid shellscript where
the pattern file is mungable. . . . .
I guess I will modify calendar to use GNU egrep. . . .
