egrep, fgrep, grep are still broken in Fedora 9 and Red Hat Enterprise Linux
Server release 5.2 (Tikanga). It is easy to get segfaults and infinite loops:

[pacman labyrinth bug]$ dd if=/dev/zero of=zero300 bs=1024k count=300
300+0 records in
300+0 records out
314572800 bytes (315 MB) copied, 4.99563 s, 63.0 MB/s
[pacman labyrinth bug]$ /bin/grep a zero300 
Segmentation fault (core dumped)
[pacman labyrinth bug]$ dd if=/dev/zero of=zero280 bs=1024k count=280
280+0 records in
280+0 records out
293601280 bytes (294 MB) copied, 4.42342 s, 66.4 MB/s
[pacman labyrinth bug]$ /bin/grep a zero280 
^C <---- seems like grep will loop forever so I interrupted it


If you remove:

  grep-mem-exhausted.patch

then the problem goes away.
