Bug #13672: Memory leak

From: mh@bang.ca Operating system: RH Linux (2.2.16-22) PHP version: 4.0.6 PHP Bug Type: Scripting Engine problem Bug description: Memory leak Doing mtrace on libphp4.so returns: - 0000000000 Realloc 6161 was never alloc'd - 0000000000 Realloc 6163 was never alloc'd - 0000000000 Realloc 6168 was never alloc'd - 0000000000 Realloc 7007 was never alloc'd - 0000000000 Realloc 7015 was never alloc'd - 0000000000 Realloc 7023 was never alloc'd Memory not freed: ----------------- Address Size Caller 0000000000 0 at I have tried the latest CVS build, but it won't compile with zlib: zlib.c:115: `STANDARD_MODULE_HEADER' undeclared here (not in a function) zlib.c:115: initializer element is not constant zlib.c:115: (near initialization for `php_zlib_module_entry.name') zlib.c:116: warning: initialization from incompatible pointer type zlib.c:117: warning: initialization from incompatible pointer type zlib.c:122: warning: initialization from incompatible pointer type zlib.c:123: `NO_VERSION_YET' undeclared here (not in a function) zlib.c:123: initializer element is not constant zlib.c:123: (near initialization for `php_zlib_module_entry.global_shutdown_func') zlib.c:124: warning: initialization makes integer from pointer without a cast zlib.c:124: warning: initialization makes integer from pointer without a cast zlib.c:124: warning: initialization makes integer from pointer without a cast zlib.c:124: warning: excess elements in struct initializer zlib.c:124: warning: (near initialization for `php_zlib_module_entry') zlib.c:125: warning: excess elements in struct initializer zlib.c:125: warning: (near initialization for `php_zlib_module_entry') make[3]: *** [zlib.lo] Error 1 make[3]: Leaving directory `/usr/local/bang_setup/php4-200110141200/ext/zlib' make[2]: *** [all-recursive] Error 1 make[2]: Leaving directory `/usr/local/bang_setup/php4-200110141200/ext/zlib' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/local/bang_setup/php4-200110141200/ext' make: *** [all-recursive] Error 1 My config line for PHP is: --with-apxs=/usr/local/apache/bin/apxs' '--enable-force-cgi-redirect' '-with-png-dir=/usr/local/bang_setup/libpng-1.0.11/' '--with-zlib-dir=/usr/local/bang_setup/zlib-1.1.3/' '--enable-ftp' '--with-gd=/usr/local/bang_setup/gd-1.8.4' '--with-jpeg-dir=/usr/local/' '--with-mysql=/usr/local' '--enable-gd-imgstrttf' '--with-imap' '--with-ldap=/usr/local' '--enable-gd-native-ttf' '--enable-trans-sid' '--with-mcrypt' Some of our websites have become erratic, to the point where some scripts would sometimes return: Cannot use assign-op operators with overloaded object s nor string offsets on something as simple as $table[$i] .= "something"; This last problem has been circumvented by $var .= "something"; $table[$i] = $var; but now rather than the above-mentioned error, the script outputs the letter "F". I wish I could be more accurate, but I have no idea why this started happening, but I suspect the memory leak. I haven't been able to come up with a test case, and my script is a little unwieldy. -- Edit bug report at: http://bugs.php.net/?id=13672&edit=1
