In fact I wrote it to fix a perf top issue. What 'issue' and why wasn't it described in the changelog more accurately? The blurb you wrote in the changelog: | The libbfd C++ demangler doesn't seem to deal with cloned functions, | like symbol.clone.NUM. | | Just strip the dot part before demangling and add it back later. Only alludes to a C++ symbol resolution annoyance and thus isn't very informative. Ingo
