_very_ specific memory leak in Zend

With the latest php4 cvs, I am getting the following in my apache error log: [Fri Apr 14 22:44:32 2000] Script: '/var/www/horde/imp/test.php' --------------------------------------- ./zend-scanner.l(213) : Block 0x081D21E8 status: Beginning: OK (allocated on ./zend-scanner.l:544, 16 bytes) End: Overflown (magic=0x2A8FCC00 instead of 0x2A8FCC84) 1 byte(s) overflown --------------------------------------- ./zend-scanner.l(544) : Freeing 0x081D220C (16 bytes), script=/var/www/horde/imp/test.php Here is the simplest test script I have found that reproduces the problem: <?php use './fishfooder'; ?>done Here's where it gets tricky: it seems to depend on the number of characters in the filename. Some longer ones don't generate the error, some do; no shorter ones that I tried generated it, but I didn't do an exhaustive search. Slashes ('/') indicating directories _do_ count in the number of characters. require() does not generate the error. Also, the file must exist, but it does not have to be anything in it - fishfooder.php is a completely empty file for the purposes of the above script. Hopefully this is enough detail to track down the problem. -chuck
