<pre>I found my LO hangs when open "wrong" file from CIFS
under very specific conditions:
1.0. CIFS mount point on Synology NAS (Samba 4.4.16). Can't reproduce on Samba
from desktop Linux. Can't reproduce from Windows share.
2.0. SAL_ENABLE_FILE_LOCKING should be set. Even to empty
SAL_ENABLE_FILE_LOCKING= Same issue for 0 and 1.
3.1. echo "test" > test.odt
3.2. test.txt work fine, but test.{odp|odt|doc|docx|etc.} fails
I'm use Gentoo ebuild.
With debuginfo I have this backtrace for app-office/libreoffice-6.3.3.2:
$ cd /mnt/mountpoint
$ echo "test" > test.odp
$ $ SAL_ENABLE_FILE_LOCKING= gdb /usr/lib64/libreoffice/program/soffice.bin
GNU gdb (Gentoo 8.3.1 vanilla) 8.3.1
This GDB was configured as "x86_64-pc-linux-gnu".
(gdb) run --writer test.odp
Starting program: /usr/lib64/libreoffice/program/soffice.bin --writer test.odp
