Hi, thanks. I'm able to open that DPX file on my end (not on Windows), so I
don't think it's a corrupt file.
Can you build all of OIIO in Debug mode (not Release) and use the debugger to
find out what file and line is where the actual crash is occurring? The
screenshot you provided only shows where in your unit test it was, so the
actual crash could be practically anywhere inside what happens within the
open() call.
I'm sorry I'm not easily able to help, I don't have access to a Windows machine.
Can somebody else out there who uses OIIO on Windows please do us a favor and
download this DPX file in the links below, then try anything that forces an
open (e.g., 'iinfo -v -stats blah.dpx') and report what happens? Does this
crash for everybody? If anyone can reproduce, do you have any ideas or can you
get closer to finding what line within the OIIO code is the source of the
problem?
