Comment 4 for bug 679390

This MUST be 3.2, because the bug was filed with hugin 2009.2 which was released before enblend 4.0 came out.

It seems to me that this is either an imagecache bug which we know is buggy, or it's trying to blend too large an image for a 32bit machine.

The alloc that fails is reasonable in the context of the stitch that is going on. At 16k x 8k pixels, we have 128M pixels. At 4 bytes per pixel, we have 512Mbytes of memory.

And if you need to allocate a few images, like source1, source2, destination, you quickly run out of addressing space on a 32bit machine....
