Unfortunately, I'm getting segmentation faults. When I switch to PHP 5.6.18, everything works fine. I saved the relevant core dump files from Apache. Unfortunately, I don't know how to trace which Apache requests or what PHP code triggers the problem. #0 zend_string_release (s=0x7fe420712a28) at /src/php-7.0.3/Zend/zend_string.h:269 #1 zend_hash_destroy (ht=0x7fe42c1c43c0 <pcre_globals>) at /src/php-7.0.3/Zend/zend_hash.c:1273 #2 0x00007fe42b867919 in module_destructor (module=module@entry=0x7fe42f16b530) at /src/php-7.0.3/Zend/zend_API.c:2509 #3 0x00007fe42b86049c in module_destructor_zval (zv=<optimized out>) at /src/php-7.0.3/Zend/zend.c:615 #4 0x00007fe42b872389 in _zend_hash_del_el_ex (prev=<optimized out>, p=<optimized out>, idx=<optimized out>, ht=<optimized out>) at /src/php-7.0.3/Zend/zend_hash.c:1013 #5 _zend_hash_del_el (p=0x7fe42f1838d0, idx=4, ht=0x7fe42c1cb2c0 <module_registry>) at /src/php-7.0.3/Zend/zend_hash.c:1037 #6 zend_hash_graceful_reverse_destroy (ht=ht@entry=0x7fe42c1cb2c0 <module_registry>) at /src/php-7.0.3/Zend/zend_hash.c:1489 #7 0x00007fe42b865ddc in zend_destroy_modules () at /src/php-7.0.3/Zend/zend_API.c:1977 #8 0x00007fe42b861455 in zend_shutdown () at /src/php-7.0.3/Zend/zend.c:840 #9 0x00007fe42b8059cb in php_module_shutdown () at /src/php-7.0.3/main/main.c:2352 #10 0x00007fe42b805a89 in php_module_shutdown_wrapper (sapi_globals=<optimized out>) at /src/php-7.0.3/main/main.c:2320 #11 0x00007fe42b8f1b51 in php_apache_child_shutdown (tmp=<optimized out>) at /src/php-7.0.3/sapi/apache2handler/sapi_apache2.c:399 #12 0x00007fe42cdf4fae in run_cleanups (cref=<optimized out>) at memory/unix/apr_pools.c:2352 #13 apr_pool_destroy (pool=0x7fe42f2be8d8) at memory/unix/apr_pools.c:814 #14 0x00007fe42e22975e in clean_child_exit (code=0) at prefork.c:227 #15 0x00007fe42e229c48 in child_main (child_num_arg=544287272, child_bucket=-1104392960) at prefork.c:744 #16 0x00007fe42e229ff0 in make_child (s=0x7fe42f013248, slot=172, bucket=0) at prefork.c:824 #17 0x00007fe42e22adb5 in perform_idle_server_maintenance (p=<optimized out>) at prefork.c:932 #18 prefork_run (_pconf=0x7fe420712a28, plog=0x7ffebe2c4dac, s=0x7ffebe2c4db0) at prefork.c:1128 #19 0x00007fe42e1ac27e in ap_run_mpm (pconf=0x7fe42efe0138, plog=0x7fe42f019818, s=0x7fe42f013248) at mpm_common.c:94 #20 0x00007fe42e1a5845 in main (argc=3, argv=0x7ffebe2c5088) at main.c:777 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71662&edit=1
