Bug#961345: cups: daemon crashes with invalid free()

[Bernhard Übelacker <bernhardu@mailbox.org>]

Hello Ronny,
sorry for the delay.
You wrote you recompiled - then I guess your build directory should
also contain the libcups2-dbgsym and cups-daemon-dbgsym packages.

If you still get this crash, could you install these dbgsym packages
from your build and recreate that backtrace in coredumpctl?
A 'bt full' could contain some details too.

Otherwise running cupsd within valgrind could also give some hints.


This bug might describe the same issue, unfortunately also without solution:
