Comment 5 for bug 1814146

Unfortunately, after using the system for a couple of days, I received another BSOD in qxldd.sys.

I started to look into linking the binary I built when it looks like it is already using it. Here's what is currently being used:

ldd /usr/bin/qemu-system-x86_64 | grep spice
 libspice-server.so.1 => /usr/local/lib/libspice-server.so.1 (0x00007fac29f23000)

ll /usr/local/lib/libspice-server.so.1
lrwxrwxrwx 1 root root 25 Apr 12 09:52 /usr/local/lib/libspice-server.so.1 -> libspice-server.so.1.12.5

dpkg -S /usr/local/lib/libspice-server.so.1
spice: /usr/local/lib/libspice-server.so.1

sudo apt list spice
Listing... Done
spice/now 0.14.1.143-20190412-1 amd64 [installed,local]

And here is the contents of the package that I built before installing yours from the PPA:

dpkg --contents spice_0.14.1.143-20190412-1_amd64.deb | grep libspice-server.so
-rwxr-xr-x root/root 1202224 2019-04-12 09:52 ./usr/local/lib/libspice-server.so.1.12.5
lrwxrwxrwx root/root 0 2019-04-12 09:52 ./usr/local/lib/libspice-server.so -> libspice-server.so.1.12.5
lrwxrwxrwx root/root 0 2019-04-12 09:52 ./usr/local/lib/libspice-server.so.1 -> libspice-server.so.1.12.5

I've uninstalled the PPA, uninstalled my package, and then reinstalled the PPA.

So, now we're back on the distro's version of spice. Reinstalling your PPA.

Ok, now it looks like we're on your version. I'll continue testing with this.

That said, it looks like I inadvertently skipped to the last recommendation you made (the installation of the PPA I think helped to link to my built binary, which was present on the system in /usr/local/ when I installed the PPA), which is off of a more recent commit than the bug referenced in the Red Hat ticket:
5efc8fc8 -= Francois Gouget, 12 days ago : video-stream: use the dcc local variable

Will continue testing now that I have confirmed your version is installed and being used, just in case something later in that git repo broke it again.
