| Description: | During CLI "core stop gracefully", valgrind detects an invalid read in __ast_context_destroy:
{noformat} ==6990== Invalid read of size 1 ==6990== at 0x4C2B89E: strcasecmp (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==6990== by 0x58DA11: __ast_context_destroy (pbx.c:10671) ==6990== by 0x58E298: ast_context_destroy (pbx.c:10816) ==6990== by 0x1325985B: unload_module (func_periodic_hook.c:454) ==6990== by 0x53CF38: ast_module_shutdown (loader.c:610) ==6990== by 0x4543B0: really_quit (asterisk.c:1961) ==6990== by 0x454049: quit_handler (asterisk.c:1876) ==6990== by 0x455306: handle_stop_gracefully (asterisk.c:2371) ==6990== by 0x4DB118: ast_cli_command_full (cli.c:2719) ==6990== by 0x4DB263: ast_cli_command_multiple_full (cli.c:2742) ==6990== by 0x452F0E: netconsole (asterisk.c:1516) ==6990== by 0x602F83: dummy_start (utils.c:1232) ==6990== Address 0xd1fa190 is not stack'd, malloc'd or (recently) free'd {noformat} Occasionally the leak will be detected as coming from previously freed memory from another unrelated random portion of the code -- for which reason I believe this is a corrupted pointer rather than reference to free'd memory. | ||
