The Double Edge Mask node uses too much memory when it is not connected to anything in the Full-Frame compositor. That's because it tries to allocate a buffer of size 131072x131072, which is due to the cumulation of multiple issues. 1. The Full-Frame compositor evaluates nodes that are not connected to the output. 2. The constant folder assigns a bounds of +-65536 to its output memory buffers as a maximum possible value. 3. Then the MemoryBuffer::inflate method doesn't know about the constant folder special value, so it tries to allocate a buffer of that size. The safest fix for now is to clear the output and return early if all inputs are single value. The problem is that this issue might happen for other nodes that also satisfy the 3 issues above, that is, uses inflate and can be constant folded. I manually checked for such nodes and there are no nodes that satisfy all three, so hopefully this is isolated to the Double Edge Mask node.
