Alright, thank you for giving it a look. As far as I can see from libmesh’s config.log the CXXFLAGS_DBG do include the option -O0.
For the others I cannot really do much at the moment because I am in a somewhat unfortunate situation, where: I have a filesystem on the cluster that I can compile stuff on but to which the compute nodes, i.e. also the debugger, have no access to. I can use the framework compiled by the computational center that’s located on a filesystem that is accessible but I cannot perform any changes on. My local computer is a mac and gdb does not work with the dynamic library version of macOS Sierra. (I am restricted to the GNU compilers) But I will try and figure something out where I can have access both to a large enough filesystem that’s accessible and to a working debugger. I will keep you posted.
