Subject: Fixed the bug in searching for triple quotes -- change the 'quote2'
X-Git-Tag: v1.5.1~739
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=35685240a91dbb3e4fb0e0b343019ba586e531c2;p=thirdparty%2FPython%2Fcpython.git

Fixed the bug in searching for triple quotes -- change the 'quote2'
variable from a pointer to an index, so a realloc() of the buffer
won't disturb it.  Problem found by Vladimir Marangozov.
