Protocol error when using strip over shared folders.

[kwhat]

Steps to reproduce: Share a folder to a Linux guest. Copy a dll file to the share folder. (I used the taskschd.dll to test) On the linux guest run strip /path/to/mounted/share/taskschd.dll and you get "strip:./st9tAIQu: Protocol error" Now to prove a point copy that dll to somewhere on the guest disk, cp /path/to/mounted/share/taskschd.dll /tmp ; strip /tmp and notice that there is no error.

I have absolutely no idea why this only happens with dll files. I am able to strip shared object files without issue. I am also able to strip dll files on windows using mingw from shared folders with no issues. This happens with every dll I have tired. Both the guest and host OS are gentoo.

I am running into the same problem. I have not yet figured out a fix or a work-around. I am running VirtualBox 4.12 on a Mac OSX 10.8 host with a Debian Squeeze guest.

EDIT: I am using the 4.12 version of the Guest Additions as well:

I have the same problem when running Ubuntu-12.04 64 Bit VM on Ubuntu-13.10 64 Bit. strip does not work on a shared folder:

$ i686-w64-mingw32-strip zlib1.dll
i686-w64-mingw32-strip:st7VXEcU: Protocol error

Module for shared folders is:
