I don't understnad why the Debian should have grep 2.4.2 even in the
unstable branch.
AFAIK, version 2.5 is what distributions should use nowadays.

I've verified that grep 2.5 handles your regexes correctly, so I think
you (or Debian) should upgrade.  (But the problem may be on the side of
glibc, grep often uses glibc regex implementation.)
Perhaps you have to file a request to Debian bug tracking system.

Note: When building grep 2.5, you should not beleive ``make check'';
there is one false bug report there.  (And you have to chmod +x the
scripts to even run ``make check''.) Sorry for the inconvenience.

For an unstable branch, there is even an unstable alternative: version
2.5.1.  Currently available from the CVS only, probably by this command:
  cvs -z3 -d:pserver:address@hidden:/cvs co grep

HTH,
