Previous Comments: ------------------------------------------------------------------------ [2015-07-08 13:53:45] suralc dot github at gmail dot com Description: ------------ Note: I am aware that the file based opcache is experimental. Compiled php (master@f9dc60f36f0c03) using visual studio 2015(RC) on the latest windows 10 build (x64 host and built) using configure --enable-debug --with-openssl --enable-opcache-file --without-gd Opcache config: opcache.enable=1 opcache.enable_cli=1 opcache.file_cache=e:\programme\dev\php7\tmp opcache.file_cache_only=1 Setting file_cache_only to 0 prevents the crash. Running phpunit executes the tests fine (and prints results) but crashes afterwards: First guess is that p->key->gc.u.v which is accessed by the GC_FLAGS macro which is "called" by the ZSTR_IS_INTERNED macro is already free when execution reaches accel_reset_pcre_cache. (See the output below) I was unable to reproduce the crash outside of that environment(phpunit) so far. Actual result: -------------- >? p->key->gc.u.v {type=??? flags=??? gc_info=??? } type: <Speicher kann nicht gelesen werden> flags: <Speicher kann nicht gelesen werden> gc_info: <Speicher kann nicht gelesen werden> >? p->key->gc {refcount=??? u={v={type=??? flags=??? gc_info=??? } type_info=??? } } refcount: <Speicher kann nicht gelesen werden> u: {v={type=??? flags=??? gc_info=??? } type_info=??? } Ausnahmefehler bei 0x00007FFD06498C8E (php_opcache.dll) in php.exe: 0xC0000005: Zugriffsverletzung beim Lesen [Access violation while reading] an Position 0x0000006DF1603925 > php_opcache.dll!accel_reset_pcre_cache() Zeile 1976 C php_opcache.dll!accel_shutdown() Zeile 2676 C php_opcache.dll!zm_shutdown_zend_accelerator(int type, int module_number) Zeile 420 C php7ts_debug.dll!module_destructor(_zend_module_entry * module) Zeile 2513 C php7ts_debug.dll!module_destructor_zval(_zval_struct * zv) Zeile 603 C php7ts_debug.dll!_zend_hash_del_el_ex(_zend_array * ht, unsigned int idx, _Bucket * p, _Bucket * prev) Zeile 936 C php7ts_debug.dll!_zend_hash_del_el(_zend_array * ht, unsigned int idx, _Bucket * p) Zeile 960 C php7ts_debug.dll!zend_hash_graceful_reverse_destroy(_zend_array * ht) Zeile 1406 C php7ts_debug.dll!zend_destroy_modules() Zeile 1990 C php7ts_debug.dll!zend_shutdown() Zeile 839 C php7ts_debug.dll!php_module_shutdown() Zeile 2346 C php.exe!main(int argc, char * * argv) Zeile 1355 C [Externer Code] ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=70022&edit=1
