Bug report
Steps To Reproduce?
Additional InformationA trivial fix could be:

if (ht && zend_hash_find(ht, element, element_length + 1, (void **) &retval_pp) == SUCCESS) {
    if (retval_pp) {
      retval_p = *retval_pp;
    goto cleanup;

But I don't enough about XDebug internals and if this is revelant.
Else, corrupted value in retval_pp could show some memory corruption.
TagsNo tags attached.
Operating System

Sorry, but I can't see how that situation can be reached. I can't reproduce it and your linked reports have no reproducible script either. I'm afraid I'll have to close it unless there is more information.
