> Summary: fatal internal error w/ZendEngine2
>
> Initial Comment:
> a user reported this via the Gentoo bugzilla ... when
> trying to build the ZendEngine2 in php cvs, flex dies:
>
> wget \
> 'http://cvs.php.net/viewcvs.cgi/*checkout*/ZendEngine2/flex.skl'
> wget \
> 'http://cvs.php.net/viewcvs.cgi/*checkout*/ZendEngine2/./zend_language_scanner.l'
> flex -Pzend -S./flex.skl -ozend_language_scanner.c \
>  -i ./zend_language_scanner.l
> flex: fatal internal error, bad line in skeleton file
>
> looks like it's due to the usage of '%*', '%+', and
> '%-' in the flex.skl file, but i'm not lex expert and
> i'm just guessing at this point :)

> They appear to be using a custom skeleton. The skeleton has
> changed significantly since past releases.
>
> If they _really_ need their own skeleton, I suggest they
> create a patch between the flex 2.5.4 skeleton and their own
> skeleton to identify the differences. Then, using that patch
> merely as a guide, patch the 2.5.33 skeleton BY HAND to
> upgrade it. However, I suspect they don't really need the
> custom skeleton.
>
> Please have someone from the Zend team contact me directly
> so I can help them refactor their code to use flex 2.5.33.
