Previous Comments: ------------------------------------------------------------------------ [2021-08-12 11:08:17] nikic@php.net Does this issue still occur? I can reproduce this with PHP 7.4 compiled without valgrind, but not when compiled with valgrind. Since PHP 8.1, having valgrind available at compilation time is not necessary anymore, a valgrind-friendly implementation is automatically picked at runtime. ------------------------------------------------------------------------ [2020-04-08 15:38:52] maxsem dot wiki at gmail dot com Tried, still see the errors: $ php -i|grep configure Configure Command => './configure' '--enable-debug' '--with-readline' '--with-valgrind' ------------------------------------------------------------------------ [2020-04-08 07:44:21] nikic@php.net Please make sure that valgrind headers are available at configure time. You can also specify --with-valgrind to enforce this. ------------------------------------------------------------------------ [2020-04-07 20:45:57] maxsem dot wiki at gmail dot com Description: ------------ Running php compiled from git master, revision 4e69970fb746970655a865cee116c91b7b09d36b $ valgrind php -r 'echo "foo";' ==17149== Memcheck, a memory error detector ==17149== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==17149== Using Valgrind-3.14.0 and LibVEX; rerun with -h for copyright info ==17149== Command: php -r echo\ "foo"; ==17149== ==17149== Conditional jump or move depends on uninitialised value(s) ==17149== at 0x70DEB4: zend_string_equal_val (zend_string.c:403) ==17149== by 0x6E3928: zend_string_equal_content (zend_string.h:310) ==17149== by 0x6E5BDE: zend_hash_find_bucket (zend_hash.c:644) ==17149== by 0x6EAE2D: zend_hash_find (zend_hash.c:2220) ==17149== by 0x6523CB: cfg_get_entry_ex (php_ini.c:900) ==17149== by 0x6470B3: php_get_configuration_directive_for_zend (main.c:1589) ==17149== by 0x6D24E1: zend_get_configuration_directive (zend.c:1246) ==17149== by 0x6F77BF: zend_register_ini_entries (zend_ini.c:245) ==17149== by 0x64843A: php_module_startup (main.c:2239) ==17149== by 0x7A38FF: php_cli_startup (php_cli.c:402) ==17149== by 0x7A562A: main (php_cli.c:1318) ==17149== ==17149== Conditional jump or move depends on uninitialised value(s) ==17149== at 0x70DEB4: zend_string_equal_val (zend_string.c:403) ==17149== by 0x70D2FB: zend_string_equal_content (zend_string.h:310) ==17149== by 0x70D962: zend_interned_string_ht_lookup (zend_string.c:154) ==17149== by 0x70DA7A: zend_new_interned_string_permanent (zend_string.c:194) ==17149== by 0x6F7829: zend_register_ini_entries (zend_ini.c:248) ==17149== by 0x64843A: php_module_startup (main.c:2239) ==17149== by 0x7A38FF: php_cli_startup (php_cli.c:402) ==17149== by 0x7A562A: main (php_cli.c:1318) ==17149== ==17149== Conditional jump or move depends on uninitialised value(s) ==17149== at 0x70DEB4: zend_string_equal_val (zend_string.c:403) ==17149== by 0x6E3928: zend_string_equal_content (zend_string.h:310) ==17149== by 0x6E818F: zend_hash_del (zend_hash.c:1361) ==17149== by 0x6E0CE7: zend_declare_typed_property (zend_API.c:3588) ==17149== by 0x6E1600: zend_declare_property_ex (zend_API.c:3775) ==17149== by 0x6E1665: zend_declare_property (zend_API.c:3782) ==17149== by 0x6E1761: zend_declare_property_long (zend_API.c:3811) ==17149== by 0x3F6C48: zm_startup_dom (php_dom.c:589) ==17149== by 0x6DA6F8: zend_startup_module_ex (zend_API.c:1751) ==17149== by 0x6DA753: zend_startup_module_zval (zend_API.c:1766) ==17149== by 0x6E992C: zend_hash_apply (zend_hash.c:1815) ==17149== by 0x6DAD52: zend_startup_modules (zend_API.c:1877) ==17149== foo==17149== ==17149== HEAP SUMMARY: ==17149== in use at exit: 1,094 bytes in 20 blocks ==17149== total heap usage: 12,317 allocs, 12,297 frees, 1,763,396 bytes allocated ==17149== ==17149== LEAK SUMMARY: ==17149== definitely lost: 0 bytes in 0 blocks ==17149== indirectly lost: 0 bytes in 0 blocks ==17149== possibly lost: 0 bytes in 0 blocks ==17149== still reachable: 1,094 bytes in 20 blocks ==17149== suppressed: 0 bytes in 0 blocks ==17149== Rerun with --leak-check=full to see details of leaked memory ==17149== ==17149== For counts of detected and suppressed errors, rerun with: -v ==17149== Use --track-origins=yes to see where uninitialised values come from ==17149== ERROR SUMMARY: 262 errors from 3 contexts (suppressed: 0 from 0) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=79457&edit=1
