Syslinux - Jul 2013 - VirtualBox virtual machine hangs after ISOlinux upgrade 4.05->5.10 and up.

Hello,
I have specialized linux installation which uses ISOLinux bootloader. Recently
isolinux version has changed from 4.05 to 5.10. From that time there is a
problem with VirtualBox VM, It crashes (guru meditation) on attempt to boot from
HDD or hangs on installation from CD.
Strange part is, the very same ISO on ESXi VM works like a charm. Also burned on
CD and started on "real" hardware works.

Tried VirtualBox 4.1.14 on Linux and Windows 4.1.12. Tried to change VM
settings, no luck.

After "Guru meditation" crash there is a log file with last line:
fatal error in recompiler cpu: Trying to execute code with memory type
addr_code=00000000631b0020 addend=00007fceea68e000 at 00000000631b04fd.
(iHandlerMemType=0x38 iMMIOMemType=0x30)

I will appreciate any help, Thank You.

That's quite an old version - 4.2.16 is out. Have you tried it on that?

I would suggest, for the purpose of testing Syslinux 5.xx (and its 
variants), to update to VBox 4.2.x.

Didn't know there was any question on the Syslinux 5.10 released 
version. I upgraded my g4l image, and do testing with the latest 
virtualbox built from the source from the site with 4.2.16 and at 
least one previous version. My image has 8 kernels going back to 
3.0.87 to 3.11-rc2 and they run fine under virtualbox with 5.10. 
Also, the memtest 4.20 runs fine, as does the HDT included with 
5.10.

Have not tried any of the 6.x version, but had tired some older 5.x 
versions, and after getting help on making changes to the 
syslinux.cfg file, and adding some of the additional .c32 files have 
had no issues. Unfortunately, don't have any efi systems to test 
that kind of stuff on...

Thanks again for all the work...
