That assertion appears to be associated with an ImageBuf copy constructor. I'm not sure how it can happen for the constructor ImageBuf(ImageSpec&, void*buffer).
Are you sure you're not hitting the assertion at some point other than when you first construct it as in your example? Maybe... is it possible you have a function that's intended to receive an ImageBuf&, but instead you mis-declared the function as taking an 'ImageBuf' so it's passing by value and copy-constructing, instead of passing by reference? (It's also possible it's ME who is doing that somewhere.) I don't suppose I could convince you to use a DEBUG-compiled build of OIIO and try to catch it in the debugger and show us the full stack trace? On my end, I'll try to figure out why I have that assertion there.
