validate_plperl_function() supposed that it could free an old plperl_proc_desc struct immediately upon detecting that it was stale. However, if a plperl function is called recursively, this could result in deleting the struct out from under an outer invocation, leading to misbehavior or crashes. Add a simple reference-count mechanism to ensure that such structs are freed only when the last reference goes away. Per investigation of bug #7516 from Marko Tiikkaja. I am not certain that this error explains his report, because he says he didn't have any recursive calls --- but it's hard to see how else it could have crashed right there. In any case, this definitely fixes some problems in the area. Back-patch to all active branches. |
