Issue: https://github.com/php/php-src/issues/12974 Author: stable-staple ### Description **Problem Scenario:** Start Apache (version 2.4.58). Execute any PHP script that uses pg_pconnect function to establish a PostgreSQL persistent database connection (host=<host> port=<port> dbname=<dbname> user=<user>). Stop Apache. **Observed Behavior:** After stopping Apache, dump files are generated. The dump files include backtrace information: ``` EXCEPTION_RECORD: (.exr -1) ExceptionAddress: 00007ffe1399c5a0 (php_pgsql+0x000000000000c5a0) ExceptionCode: c0000005 (Access violation) ExceptionFlags: 00000000 NumberParameters: 2 Parameter[0]: 0000000000000008 Parameter[1]: 00007ffe1399c5a0 Attempt to execute non-executable address 00007ffe1399c5a0 ... 0000009827eff2e8 00007ffe0e8b048a : 0000021e610ff298 0000021e61233070 0000021e5c7cf510 0000021e59870000 : php_pgsql+0xc5a0 0000009827eff2f0 00007ffe0e8828b2 : 0000000000000000 00007ffe00000000 0000000000000168 00007ffe313237eb : php8ts!zend_register_list_destructors_ex+0x10a 0000009827eff320 00007ffe0e7d47ca : 0000000000000009 0000000000000009 0000000000000168 0000021e59870000 : php8ts!zend_hash_graceful_reverse_destroy+0x1d2 0000009827eff370 00007ffe0e947d52 : 0000000000000000 0000000000000000 0000021e59919438 00007ffe313237eb : php8ts!zend_append_version_info+0xcba 0000009827eff3a0 00007ffe0e7d1982 : 0000021e59919458 000000005a27cb50 0000021e59919438 0000000000000000 : php8ts!ts_free_id+0xc2 0000009827eff3f0 00007ffe0e91bab6 : 0000021e5c0be2b8 0000000000000000 0000021e5c0be168 0000000000000000 : php8ts!zend_alloc_ce_cache+0x6c2 0000009827eff420 00007ffe0e91bb49 : 0000021e5c0be1e0 0000021e614951b0 0000000000000000 0000021e5987ae50 : php8ts!php_module_shutdown+0x36 0000009827eff450 00007ffe2a343288 : 0000021e5987ae50 0000021e5c0be188 0000021e59894f70 000000005a27cb50 : php8ts!php_module_shutdown_wrapper+0x9 0000009827eff480 00007ffe0fbdffbe : 0000021e5987ae50 0000021e599133e0 0000000000000000 000000000000ea60 : php8apache2_4+0x3288 0000009827eff4b0 00007ffe0fbdf429 : 0000000000000000 000000005a27cb50 000000000000ea60 000000005a27cb50 : libapr_1!apr_pool_userdata_get+0xe348 0000009827eff4e0 000000005a23983c : 0000000000000000 000000005a27cb50 0000000000000780 0000000000000001 : libapr_1!apr_pool_userdata_get+0xd7b3 0000009827eff510 000000005a23f59c : 0000000000000017 0000021e5987ae50 0000021e598c43f8 000000005a2512b6 : libhttpd!ap_get_server_revision+0x2766c 0000009827eff5e0 000000005a243e3b : 0000021e5987ae50 0000021e598dc0a8 0000000000000000 0000021e5988938f : libhttpd!ap_get_server_revision+0x2d3cc 0000009827eff630 00007ff7878922bb : 000000005a297028 0000021e598a2678 0000009827eff6c9 0000021e5989f2d0 : libhttpd!ap_get_server_revision+0x31c6b 0000009827eff660 00007ff787893c28 : 0000000000000003 0000021e5988a730 0000000000000064 0000000000000000 : tc_webmgr+0x22bb 0000009827eff730 00007ffe31d6257d : 0000000000000000 0000000000000000 0000000000000000 0000000000000000 : tc_webmgr+0x3c28 0000009827eff770 00007ffe33f8aa58 : 0000000000000000 0000000000000000 0000000000000000 0000000000000000 : kernel32!BaseThreadInitThunk+0x1d 0000009827eff7a0 0000000000000000 : 0000000000000000 0000000000000000 0000000000000000 0000000000000000 : ntdll!RtlUserThreadStart+0x28 ``` **Expected Outcome:** The script should execute without issues. ``` ``` ### PHP Version 8.1.25 ### Operating System Windows 11
