I've been trying to render a large image with the new beta and when I attempt to
do so I receive the error "Failed to start render: bad allocation".  The image
is slightly more than 16000 pixels wide and I'm using +FT and Display=Off.  It
will also crash at random upon clicking Run to start the render (I can't seem to
find a pattern to this yet - it also occasionally crashes when closing POV-Ray).
It doesn't seem to have a problem with smaller images but I haven't specifically
tried to nail down at what resolution this starts happening (though if it'll
help I'll run some tests to find out the exact resolution that causes the
problem).

I just tried it with 3.6 and it doesn't seem to have a problem starting the
render.

I'd really like to use the beta because it's going to almost halve the rendering
time for this particular image :)

Same problem here!
Seems to be appear by images larger then 10000 pixels width.
Tested with v3.7 beta8  pvengine.exe and pvengine-sse2.exe

The next beta has code which should help somewhat with this problem; the
intermediate output data (which was stored in memory) will now be stored
in a swap-backed file.

Problem with allocation is solved, BUT a new Error occur:

Errormessage:
Failed to start render: Failed to map intermediate image storage (possibly 
insufficient virtual address space).

Imagesize:
Width=8410
Height=5940

Please see the release notes which cover this exact issue.
