Bug ID: 27317
Summary: gdb crashes upon target remote :1234

Severity: normal
Priority: P2
Component: gdb
Assignee: unassigned at sourceware dot org

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 FILE
OMITTED>/kernel_debug]

Create a core file of GDB? (y or n) y
Aborted (core dumped)
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

Core dumps have a bigger size on my system, maybe they get compressed upon
upload?

A core dump of gdb isn't super useful, because it's specific
to your build of gdb. The failing executable might be useful
if the problem can be reproduced without any special setup
(maybe not in this case). A stack trace from gdb itself might
also be informative.

Backtrace from the gdb executable in question
Here would be the backtrace of the presumably buggy executable

Apart from the backtrace I could also upload the executable, but I am not sure
if it would be helpful without the rest of the code.
It's kernel code from a university course running on qemu, so reproducing the
bug would need a special setup software wise.
