> Possible invalid ptr AV with overlapped read/write on pipes
> -----------------------------------------------------------
>
> Key: THRIFT-4485
> URL: https://issues.apache.org/jira/browse/THRIFT-4485
> Project: Thrift
> Issue Type: Bug
> Components: Delphi - Library
> Reporter: Jens Geyer
> Assignee: Jens Geyer
> Priority: Critical
>
> If a read or write operation on pipes reaches the set timeout, the read/write
> operation is not properly cancelled. However, the overlapped struct gets
> freed when leaving the method, which essentially leaves the pending read or
> write operation with an undefined pointer.
> Easily reproducible with buffered transport over pipes, a combination that
> does not work at all anyways. The workaround for both problems is to not use
> buffered transport with pipes (use framed instead), and some sane tinemouts
> (not too short).
