It means Devel::DProf has gotten confused and ended up with an unbalanced call stack, if I remember correctly. I believe it means that your profiling data is garbage.

You might try Devel::Profiler. It's a pure-Perl replacement for Devel::DProf that works in some cases where Devel::DProf has trouble (albeit much slower).
