En Ubuntu 16.04 logré obtener el seguimiento de la pila de Python en Python 3.5 al:
Instalación python3-dbg
y python3-dev
:
$ sudo apt install python3-dbg python3-dev
python3-dbg
El paquete viene con una breve documentación sobre cómo usarlo, /usr/share/doc/python3-dbg/README.debug
que utilizaré en el siguiente paso.
Agregar un script auxiliar GDB desempaquetado /usr/share/doc/python3.5/gdbinit.gz
a ~/.gdbinit
:
zcat /usr/share/doc/python3.5/gdbinit.gz >> ~/.gdbinit
Ahora gdb podrá encontrar símbolos para el binario de Python y py-bt
funciona para mostrar el seguimiento de la pila de Python en gdb:
$ gdb -p 4762
