in reply to Profiling without Devel::DProf
...quick recompilation of Perl is all that is required to fix the latest segfault I'm facing. Recompiling Perl is not an option available to me at work
You can take sources of Devel::DProf from blead perl and compile it with your version of Perl. Last time I tried Devel::DProf from blead perl compiled and worked with 5.6.1 just fine.
