Was there ever a ready for this? I'thousand hitting this fault in an XP 32bit emulator, and on the same awarding it crashes at the aforementioned point for a 98SE install, and then guessing it's the same, though it just hangs and does not throw an error.
Host is 7-64bit.
I'm on 4.three.10 r93012

Getting this app running was the whole reason I'one thousand working with VM, time to retire the 15 year sometime laptop, simply I demand this app for piece of work.

This looks similar a 16bit crash. I'd be surprised if y'all get that in XP, though maybe in the Win16 WOW layer, or whatever it was called.

There is currently no fix because then far no 1 supplied a testcase which would permit to easily reproduce the problem. If you have something, please use

https://world wide web.virtualbox.org/ticket/12646

to provide information technology.

Should I adhere the .vdi for the guest (quite large) or an .iso to install (20mb or and so) of the application to the ticket? The application crashes with this mistake every time I effort and run it, so repeatable is certainly the case for me.

You lot won't be able to attach a file that big, unfortunately. I recall an ISO would be preferable, with instructions on how to reproduce unless it'southward really obvious. Do you accept the selection to put information technology up on Dropbox or similar? Y'all can PM me a link and I will take hold of information technology.

Since I never got anything...

We're still looking for a testcase which reproducibly shows the GPF. Until then, we won't exist spending any time on this consequence.

Thanks Ramshanker. I looked at the Changeset for the fix and it looks similar you put in a lot of hard work - much appreciated (not saying I understood it all but I got the full general idea). I recently got a chance to go back to looking at this with WinDbg. I'g non an proficient at using it but I did encounter the GP happened in code dealing with save\restore of MPU state so your gear up is in line with that. I take iii test cases to effort - a 16 chip Borland app, a 16 bit VB4 app, and VB.EXE (VB4 16 bit IDE - rare crash but I've seen it a few times). I actively maintain the 16 flake apps (too large\expensive to rewrite at this time), so the gear up is welcome and I'll let you know how it went as before long as the release is available. (Sorry, but I wasn't allowed to send these apps.)

If you lot have non plant a fix I have one for you lot to try. I merely posted this on my blog, and this will piece of work for you lot. The issue is the math coprocessor and 16 chip apps with the newer processors causes the GPF. This works with 32 scrap VM'due south and it has been successfull on vmware fusion and Virtualbox. The link is hither http://world wide web.lifeofageekadmin.com/set up-general-protection-fault-mod/ only here are the steps.

Download winfloat fromhttp://world wide web.conradshome.com/win31/archive/.
Click on winfloat.exe to download to a directory. Once downloaded double-click to extract the files.
Copy HIDE87.com to c:\windows\system32 directory
Add to lh c:\windows\system32\autoexec.nt file as the commencement line.
Reboot virtual motorcar

Attempt running your 16-bit application. Hope this helps!

I tin confirm the HIDE87.com trick solves the trouble because information technology stops using the MPU so finer it avoids the trouble. It also really slows down everything (unbearably for what I work on - Engineering app with lots of calculations). A proper ready is ever improve, just agreed that this solution volition become you going until a set is in place.

The set is in version 4.3.16 released yesterday. Really bad timing for such workarounds.
