Hi there, I've got some slow code, so I turned straight to Devel::NYTProf to see if I can track down the problematic areas. However, sadly running NYTProf against our code causes a buffer overflow and a stack trace, thus terminating the script.
This is the output I'm seeing, and I'm at a loss on how to fix this: l...@ollie-desktop:~/Work/acid2$ perl -d:NYTProf admin/sql/updates/ngs- migrate-edits.pl --limit 1 Upgrading edits! Here we go!
