This is actually not a GDB bug, but apparently a Linux kernel bug. I'm closing this as duplicate of Bug 1535174; feel free to follow the progress there. As a workaround, you can try using -g (and not -g3) when building grub2; this is the default RPM build flag to use anyway. Thanks. *** This bug has been marked as a duplicate of bug 1535174 *** Sorry, please disregard my last comment. (In reply to Sergio Durigan Junior from comment #2) > Sorry, please disregard my last comment. Not all of it, though. The workaround mentioned (-g instead of -g3) is still valid. I will propose a patch to the grub2 package which does that. I've created Bug 1708780 to fix this on grub2. GDB should also not crash on invalid DWARF; I'll submit a patch upstream soon.
