I'm not sure what I've done to cause this...I ran "../php -f Config.php" from "<srcdir>/pear". I have an old PEAR install under /usr/local/lib/php, and my include path is ".:/usr/local/lib/php". Here's the back trace. #0 0x40369567 in memcpy (dstpp=0x8505bb9, srcpp=0x8505a64, len=4294967295) at ../sysdeps/generic/memcpy.c:55 #1 0x80998e0 in php_fopen_with_path (filename=0x8505ae4 "PEAR.php", mode=0x8336563 "rb", path=0x8335f95 ".:/usr/local/lib/php", opened_path=0xbfffea0c) at fopen_wrappers.c:486 #2 0x8099ca8 in php_fopen_url_wrapper (path=0x8505ae4 "PEAR.php", mode=0x8336563 "rb", options=1, issock=0xbfffe940, socketd=0xbfffe93c, opened_path=0xbfffea0c) at fopen_wrappers.c:585 #3 0x80990e2 in php_fopen_wrapper (path=0x8505ae4 "PEAR.php", mode=0x8336563 "rb", options=1, issock=0xbfffe940, socketd=0xbfffe93c, opened_path=0xbfffea0c) at fopen_wrappers.c:278 #4 0x809762f in php_fopen_wrapper_for_zend (filename=0x8505ae4 "PEAR.php", opened_path=0xbfffea0c) at main.c:508 #5 0x81c7016 in execute (op_array=0x8507424) at ./zend_execute.c:2062 #6 0x8198074 in zend_execute_scripts (type=8, file_count=3) at zend.c:752 #7 0x809893f in php_execute_script (primary_file=0xbffffb7c) at main.c:1282 #8 0x80966bc in main (argc=3, argv=0xbffffc0c) at cgi_main.c:741 The attached patch turns it from a crash to a leak, as below: [Mon Jul 16 06:06:48 2001] Script: 'Config.php' --------------------------------------- fopen_wrappers.c(530) : Block 0x08505B00 status: Beginning: OK (allocated on fopen_wrappers.c:479, 21 bytes) End: Overflown (magic=0x666E6F43 instead of 0x2A8FCC84) At least 4 bytes overflown --------------------------------------- fopen_wrappers.c(479) : Freeing 0x08505B24 (21 bytes), script=Config.php Perhaps someone who better understands the fopen magic could take a look at this one?
