# title: Local buffer overrun in DYN_error() that takes down the server
|
|
# decription: We have a local buffer overrun in DYN_error(), while copying tdbb_status_vector to local_status. It seems to be the first time (DYN errors + stack trace facility) when 20 status words are not enough to store the complete error info.
