ilia, your last scanner commit broke it: http://cvs.php.net/viewvc.cgi/ZendEngine2/zend_language_scanner.l?r1=1.131.2.11.2.6&r2=1.131.2.11.2.7&pathrev=PHP_5_2&view=patch

Can you have a look?

No, actually that fixed it. :-) The previous code was from a patch of mine, and it was modifying yytext (following HEAD's lead! I had since discovered another bug where changing yytext was causing characters to be dropped, which was fixed). Then I realized this hex bug existed too, and Ilia applied my fix before releasing RC3.

The "Reproduce code" posted works as expected in RC3, so the reporter was not using RC3 as indicated. Only RC2 had this problem.

I use 5.2.1RC3-dev. I install last snapshot and now use 5.2.1RC4-dev. Bug fixed. Thanks.
