Thanks for this. I used your suggested command and can now see the
Flame Chart (Incubator). However, I only see symbol addresses, not the
actual symbolic names.

I compile with:

-O3 -pg -finstrument-functions

Do I need any other compiler/linker options to resolve the symbol names?

Best regards
David
