core dump of gdb after described error

The following output is given after trying to use gdb with a symbol file and
trying to execute target remote :1234 :


Reading symbols from kernel_debug...
DW_FORM_strp pointing outside of .debug_str section [in module /<PATH TO FI=
LE
OMITTED>/kernel_debug]
(No debugging symbols found in kernel_debug)

A problem internal to GDB has been detected,
further debugging may prove unreliable.

The symbol file should work, however I don't get why gdb would crash if it
didn't either.
I have included the core dump
