--- Comment #3 from Paul Clarke <pc at us dot ibm.com> --- The IBM Advance Toolchain supports SLES 15, where the latest version of libdw is 0.168. We'll work around the issue by reverting the commit for the version of GCC included with the Advance Toolchain. I didn't see any update to the GCC documentation regarding the disruptive nature of the change causing the problem other than "[DWARF] Version 5 requires GDB 8.0 or higher". Should there be something about libdw as well? Anything else?
