there is (partial) fix for this bug.  I'm attaching it to this mail.

(Grep CVS and RedHat rawhide both contain a patch, but this one is
better.  I'll put it to the CVS ASAP.)

The patch is not perfect, though:
take care to specify the case insensitive patterns with lowercase
letters only, like

        grep --ignore-case --only-matching '<title>.*</title>'

not:    grep --ignore-case --only-matching '<TITLE>.*</TITLE>'

The ulimate fix for this problem is to change grep to make use of the
new regex library from current GNU libc, but it presents some work to
do it right.  Thus I'm sending you this temporary solution.

Thank you very much for your bug report.
