From: willw at applied dot co dot uk Operating system: Windows XP SP2 PHP version: 5.2.0RC1 PHP Bug Type: COM related Bug description: Use of com.typelib_file in PHP.ini causes A/V
Description: ------------ Use of the com.typelib_file to set a text file containing a list of typelibs causes PHP to crash with an A/V at startup. Occurs both if PHP.exe is run from command line, or from Apache 1 via php5apache.dll. Haven't tried other combos. This worked ok in PHP4, but seems to fail in all the PHP5s that I have tested. Reproduce code: --------------- Alter a working PHP.ini so that it sets com.typelib_file to point to a text file. To see the bug, the named file must exist, and contain at least one entry. It doesn't matter whether the entry is valid. PHP.ini: ... [COM] com.typelib_file = "C:/PHP/typelib_files.txt" ... contents of typelib_files.txt: C:\WinNt\System32\activeds.tlb Expected result: ---------------- (Expected no crash) Actual result: -------------- Backtrace: NTDLL! 7c901010() begin_read(_zend_ts_hashtable * 0x00fa4c20 _php_com_typelibraries) line 28 + 12 bytes zend_ts_hash_find(_zend_ts_hashtable * 0x00fa4c20 _php_com_typelibraries, char * 0x011007e8, unsigned int 0x00000010, void * * 0x0012f764) line 208 + 9 bytes php_com_load_typelib_via_cache(char * 0x011007e8, int 0x00000000, int * 0x0012f7e8, void * * * 0x00fe5028) line 238 + 25 bytes OnTypeLibFileUpdate(_zend_ini_entry * 0x01194198, char * 0x0114fbb0, unsigned int 0x00000036, void * 0x00000000, void * 0x00000000, void * 0x00000000, int 0x00000001, void * * * 0x00fe5028) line 149 + 36 bytes zend_register_ini_entries(_zend_ini_entry * 0x00f3f0c8 ini_entries, int 0x00000003, void * * * 0x00fe5028) line 182 + 56 bytes zm_startup_com_dotnet(int 0x00000001, int 0x00000003, void * * * 0x00fe5028) line 189 + 18 bytes zend_startup_module_ex(_zend_module_entry * 0x0115af70, void * * * 0x00fe5028) line 1397 + 28 bytes zend_hash_apply(_hashtable * 0x00fa6b80 _module_registry, int (void *, void * * *)* 0x00a61780 _zend_startup_module_ex, void * * * 0x00fe5028) line 666 + 16 bytes zend_startup_modules(void * * * 0x00fe5028) line 1444 + 19 bytes php_module_startup(_sapi_module_struct * 0x10019410 apache_sapi_module, _zend_module_entry * 0x100197f8 _apache_module_entry, unsigned int 0x00000001) line 1552 + 9 bytes php_apache_startup(_sapi_module_struct * 0x10019410 apache_sapi_module) line 289 + 19 bytes php_init_handler(server_rec * 0x003f8ee8, pool * 0x003f8ec0) line 933 + 10 bytes APACHECORE! 6ff66730() APACHE! 0040100f() KERNEL32! 7c816d4f() Looking at the source, one appears to be able to fix it by editing com_dotnet/com_extension.c. The php_com_typelibraries structure is accessed before it is initialised. Moving the call to zend_ts_hash_init() above REGISTER_INI_ENTRIES() seems to fix it... but may have side effects that I don't understand. -- Edit bug report at http://bugs.php.net/?id=38400&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=38400&r=trysnapshot44 Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=38400&r=trysnapshot52 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=38400&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=38400&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=38400&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=38400&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=38400&r=needscript Try newer version: http://bugs.php.net/fix.php?id=38400&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=38400&r=support Expected behavior: http://bugs.php.net/fix.php?id=38400&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=38400&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=38400&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=38400&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=38400&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=38400&r=dst IIS Stability: http://bugs.php.net/fix.php?id=38400&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=38400&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=38400&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=38400&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=38400&r=mysqlcfg
