Description:

The server shares a local CUPS printer over SMB using samba.
Printing to the shared SMB printer causes the server's SMB daemon to segfault since package version 4.13.0-1.

Reverting back to samba-4.12.6-1 and smbclient-4.12.6-1 works around the issue.

Additional info:
* package version(s): samba-4.13.0-1, smbclient-4.13.0-1
   log.segfault.txt (4.9 KiB)
   smb.conf (1.2 KiB)

I messed up, this task should be in instance "Arch Linux", category "Packages: Extra".
Someone who has The Power, please move it there.

I created a copy[1] in "Packages: Extra" and requested this task be closed explaining the circumstances, but this did not pan out as hoped - instead, the copy in "Packages: Extra" got closed as a duplicate of this one.

Version 4.13.2-1 is still affected, I will try to get this bug report upstream.

Have you tried applying the fix from [1]? Attached PKGBUILD.diff applies the patch to the current PKGBUILD.

I was intending to sit this one out until 4.13.3, but since you handed me that PKGBUILD.diff on a silver platter I had a go and built a patched 4.13.2-1 package with that.

Can confirm, the patch for the related bug report fixes the problem for me.

Thanks for doing the heavy lifting, much appreciated.
