15801,Support for STMXCSR instruction: VERR_IEM_INSTR_NOT_IMPLEMENTED,Mop,,"VirtualBox crashes at a predictable point during the installation of Microsoft Visual C++ Resitributable (x64) version 12.0.21005 via the Visual Studio Community Installer.

The machine crashes every time the package tries to install.
I have tested with the latest development version and found it was unable to open a session for the virtual machine let alone boot it.

The host is an Intel Macbook Pro circa 2009 and the guest is Windows 7 x64 SP1.

The issue appears to be that the stmxcsr instruction defined in the Intel 80/86 istruction set is not yet implemented in VirtualBox. I am also aware that this instruction is being used more often in windows 10 software so this issue may become worse over time.

I would be very appreciative if you could implement the instruction as it is causing me a small nightmare since I rely on VirtualBox for my work.",defect,closed,other,VirtualBox 5.1.2,fixed,"instruction, stmxcsr, vcpp redist",niall.newman@…,Windows,Mac OS X
