I have two very simple scripts: page1.php: <?php echo "start page1"; ?> <? include ("page2.inc"); ?> page2.php: <div>include file page2</div> after reload page1.php 5-10 times - segmentation fault: Starting program: /usr/apache-php4/bin/httpd -X Program received signal SIGSEGV, Segmentation fault. 0x400bbc61 in chunk_alloc (ar_ptr=0x4014c580, nb=64) at malloc.c:2672 malloc.c:2672: No such file or directory.
