April 21:
Thanks for the RAW test image! I took a look at some other F600EXR images in my office today and it looks like this bug is specific to the EXR dynamic range mode being used in this particular image. F600EXR images shot in high resolution mode (HR) or in dynamic range mode (DR) should work fine. The issue with this image is related to handling of the low noise or signal to noise (SN) mode.
This problem will be fixed in the next Iridient Developer 2.3.5 update which should be available later this week.
Best regards,
