#1798: add backtrace script to cactus utils Reporter: Steven R. Brandt Status: new Milestone: Version: development version Type: enhancement Priority: minor Component: Other Comment (by Roland Haas): Is it worthwhile to have and maintain such a script? We already give the `addr2line` command line at the bottom of each `backtrace.<rank>.txt` file. Plus, often one actually needs to use `gdb` and its `info line *<address>` command \(and a core dump\) either b/c of address space randomization \(laptops\) or b/c `addr2line` is older than `gdb`. Ie. do the benefits outweigh the effort? -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/1798/add-backtrace-scr…
