16567,VirtualBox 5.1.16 crashes when I open any file on the shared folder,Une,,"As wrote in the summary, VirtualBox 5.1.16 crashes when I open any file on the folder which is assigned as the shared folder.  At that time, only the VM's window disappeared and VirtualBox Manager Window is still alive.  Virtual Box 5.1.14 didn't crash whenever I use the files on the shared folder.  I use FreeBSD 10.3-stable (r315187) as host OS and Windows 7 SP1 as guest OS.  The log file contains the following lines:

00:02:25.243750 !!Assertion Failed!!
00:02:25.243750 Expression: strchr(pszFullPath, '\0') == pszSrc + 1

VirtualBox is built by poudriere pkg builder with FreeBSD ports system.  In addition, I employ the DEBUG option to generate the additional logs to obtain the above information.  When I use VirtualBox without DEBUG option, it casts siglnal 11 and crash without any information.  ",defect,closed,shared folders,VirtualBox 5.1.16,duplicate,,,Windows,other
