I know several of you are awaiting anxiously for the next release, which will be crash version 6.0.0. I update the major number to signal a change in the embedded gdb version, which will be rebased from gdb-7.0 to gdb-7.3.1. This change is required for kernels built with gcc-4.6.1, which now defaults to using -gdwarf-4, and the currently-embedded gdb-7.0 does not support DWARF 4. If you try to use the current version of crash on such a vmlinux, it fails immediately with the message: Dwarf Error: wrong version in compilation unit header (is 4, should be 2) [in module vmlinux]" followed by: crash: vmlinux: no debugging data available I've got the upgrade done, but I'm still working out a few minor kinks that always seem to happen with a gdb upgrade. I'll release it as soon as possible. Dave
