apport information
** Tags added: apport-collected artful
** Description changed:
Due to ubuntu kernel (Ubuntu 4.13.0-36.40-generic 4.13.13) being
compiled with ""-fno-var-tracking-assignments", the debug symbols
produced are of lesser quality, i.e. $context variables are not
available.
E.g.: (systemtap needs to be installed on the system)
$> stap -L 'kernel.function("reparent_leader")'
kernel.function("reparent_leader@/build/linux-r9581B/linux-4.13.0/kernel/exit.c:632")
on Fedora (Linux 4.15.6-300.fc27.x86_64) the same command gives:
kernel.function("reparent_leader@kernel/exit.c:632") $dead:struct list_head*
$p:struct task_struct* $father:struct task_struct*
