I get this error all the time from simple recursive greps on large
source directory trees.   E.g.

$ grep -r zap *
Binary file SDE/BUILD_DBG/dist/ship.tar matches
Binary file SDE/BUILD_DBG/ship/lib/servlet-api.jar matches
grep: memory exhausted

$ grep --version
GNU grep 2.5.3

The same grep on Linux or Solaris usually works, but I think only
because virtual memory is handled differently.=20

If you watch memory consumption on windows while grep is running, it
remains flat for about 30 seconds and then starts growing in sizeable
chunks until it fails.=20=20

And BTW, there was an earlier version of grep that worked but I have
since lost the version number.
