Steps to Reproduce:
1. setup shared dirrectory in virtualbox and set working dirrectory to it
2. mkdir test && touch test/\\ && cd test
3. find .

./\/\
./\/\/\
./\/\/\/\
./\/\/\/\/\

Could you please elaborate on the above step?

Are there any RHEL/EPEL packages I need to install?

What commands should I run to setup the shared directory?

Comment 3 Ondřej Pták 2015-10-09 08:24:04 UTC

Sure I can. Here is more detailed explanation of step 1:
a) install Virtualbox https://www.virtualbox.org/wiki/Downloads
b) create VM in Virtualbox
c) install rhel-7 into that VM
d) install guest additions (needs for shared directory support, error in installing graphical driver can be ignored)
e) setup shared directory (MenuPanel:Devices->Shared Folder Settings)
f) reboot (I'm not sure if this is necessary)
e) now shared directory from host OS should be available in VM system, which looks like this:
#mount
(...)
none on /media/sf_autogit type vboxsf (rw,nodev,relatime)

I forgot to add link to instructions for d), here it is: http://linuxconfig.org/rhel-7-virtualbox-guest-additions-installation

Comment 5 Ondřej Pták 2015-10-09 08:43:05 UTC

I just tried all these steps and found 1 error.
step 2.: for some reason I'm unable to create file \ from VM, but I can create it in host VM

Comment 6 Kamil Dudka 2015-10-09 16:21:54 UTC

I have followed the above steps but find worked as expected.  It must have been something specific to your configuration.  Note that I was able to create a file named '\' from my RHEL-7 VM just fine.  In any case, this does not seem to be a bug of findutils.

Comment 8 Ondřej Pták 2015-10-26 11:39:30 UTC

Sorry for delay, I was too busy lately. Finally I found time for setting clean environment (reinstalled VirtualBox, newly created VM). This issue doesn't occurs with the same version of findutils, so the cause of this issue is somewhere else, probably filesystem kernel module or anything other broken on my environment.
