--- Comment #22 from Randy MacLeod <randy.macleod at windriver dot com> ---
Yes, the host is an x86-64-linux system running Ubuntu-16.04.1.
The cross-compiler was built using the Open Embedded (OE) build system so of
course, it's not part of Ubuntu.
I did get a better backtrace as shown below but no full symbol table/line
numbers yet.
The OE build puts the toolchain in a sysroot directory structure so I tried
running gdb using the original executable:
$ file

I'm not sure why the symbol table isn't available but I can work on that
tomorrow if needed.
