Hi,
On Windows 10 with the Pharo 6 release and the latest vm [1] I get the
following crash when attempting to save the image after doing some more
intensive computations:

# Debug console
# To close: F2 -> 'debug options' -> 'show output console'
# To disable: F2 -> 'debug options' -> 'show console on errors'
LoadLibrary(SurfacePlugin) (998: Invalid access to memory location.

location.

LoadLibrary(c:\pharo6\SurfacePlugin.dll) (998: Invalid access to memory
location.

The image take around 600MB before the crash but that is expected.
I've seen that this error was appearing before in the past.
Any suggestions of how to debug it?
Build a console VM (you should see PharoConsoleUnstripped.exe in build/vm,
buildast/vm & builddbg/vm) and run under gdb from a console window.  Make
sure the Pharo window doesn't obscure the console window so you can notice
when a crash happens.  You'll then be able to get a backtrace, see where
the illegal access is, what the system is trying to do, etc.
If you're lost in gdb, when you get the crash Skype me and we can try and
look at it together.
Cheers,
...
Andrei
