In fetch_zval_from_symbol_table

Bug report https://bugzilla.redhat.com/show_bug.cgi?id=1081000
Backtrace https://bugzilla.redhat.com/attachment.cgi?id=878990

Steps To Reproduce

?

Additional Information

A 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.

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.
