I've used ddd for debugging statically compiled code, C C++ and Fortran. It is quirky. Its weirder with MPI, as you get lots of debug windows. For dynamic languages, Perl Python and others, I use komodo from ActiveState. Been a customer of theirs since 2007 or so. Excellent tool, though with a few quirks as well. Julia has/had a native debugger, and an atom plugin, but seems to be moving towards vscode. Vscode is many things, and is highly opinionated. I've gotten the debugger to "work", albeit not being helpful for the Julia I was working on. I tried the C/Fortran plugins for it and was disappointed. I wasn't aware that totalview went OSS. I thought it was closed.
