We want to fix it in open-vm-tools but I also added a sytemd bug task to
get more opinions.
@systemd
As ConditionVirtualization=vmware should have prevented the issue in the first
place, is there any rumor or known issues of that not being reliable?

Bug description:
Hi,
Crash reports like:
vmtoolsd (11) /usr/lib/libvmtools.so.0.0.0+2839c → [stack]+1ecfc →
/usr/lib/libvmtools.so.0.0.0+4eb05 →

/usr/bin/vmtoolsd+5e98 → /usr/bin/vmtoolsd+4ce3 → /usr/bin/vmtoolsd+3ea8
The cmdline of the failing process had:
/usr/bin/vmtoolsd -n vmusr --blockFd 3
I have a disassembly thou which looks like:

We don't have much more yet.
I filed an issue upstream [2] last week in case this showed up somewhere else
as well, but haven't seen any response yet.
