I believe that I have fixed the problem in both functions. I have
created a second release candidate which has just this change. It is
available from
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre-8.00-RC2.tar.gz
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre-8.00-RC2.tar.bz2
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Testing/pcre-8.00-RC2.zip
If you use PCRE_PARTIAL_SOFT (== PCRE_PARTIAL) for "abcd*" with
"xxxabcd", you get a match, but if you use PCRE_PARTIAL_HARD, you get
PCRE_PARTIAL returned, meaning "there could be a longer match".
I am still hoping to get the full release out next week, after I have
dealt with the other issues that have been raised for the RC1 candidate.
