--- Comment #5 from Simon Marchi <simon.marchi at polymtl dot ca> ---
Ok, I got it to crash by installing the Arch Linux packages you provided on
Arch Linux system, and then:
$ /usr/bin/gdb /usr/bin/kicad -c kicad-core-gdb-crasher
I then tried using my own build of GDB, it wouldn't crash. I rebuilt the Arch
package with debug info to understand where it crashes, it's within a
frame-filter implementation. To reproduce the crash, we need this to be
loaded:
(gdb) info frame-filter
objfile /usr/lib/libgobject-2.0.so.0 frame-filters:
Priority Enabled Name
100 Yes glib
So, I was able to get the crash on master with:
$ /home/simark/build/binutils-gdb-opt/gdb/gdb -nx
--data-directory=/home/simark/build/binutils-gdb-opt/gdb/data-directory -iex
"add-auto-load-scripts-directory /usr/share/gdb/auto-load" -iex "set auto-load
safe-path /" -q /usr/bin/kicad -c ../gdb-29395/kicad-core-gdb-crasher -ex bt
-batch

PS: I think you'll find the master branch of GDB (to be GDB 13) much faster to
initially load the debug info, thanks to Tom Tromey's DWARF reader refactor. I
can really see the difference with binaries of this size, between 12 and
master.
