In function accel_preload(), variable 'preload_scripts' is allocated at line 4453 through emalloc(). All paths after this allocation will execute the cleanup against this variable at 'finish' label, except for one error handling path on failure of preload_optimize() at line 4687, which may cause a memleak. This bug is suggested by a static analysis tool, please advise. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81419&edit=1
