This bug still exists in 2013.0.0-RC2. This makes stitching large HDR
panoramas in Windows impossible, since the 32-bit version runs out of
memory for all but relatively small cases.

It may or may not be related, but the 64-bit version also uses
significantly more disk access than the 32-bit version (as in, reads
@400MB/s almost constantly, vs 80MB/s every 5-10 seconds on the 32-bit
version). This may be OpenEXR or Tiff related, but in either case is
problematic.

Title:
  hugin_hdrmerge on 64bit windows produces empty image

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  The hdrmerge step in hugin workflow: 
  hugin_hdrmerge.exe -m avg -c produces empty/blackimage (both tiff or exr) with size around 40-90k. There is no error reported in the console....

  Tested for fo 2010.4.0final and
  HuginSetup_2011.0.0-rc1_64bit_Windows.exe when open the same project
  using 32 bit version, the result is OK.

  
  As using 32bit version is slower, I tested following workaround: Copy 32 bit version of hugin_hdrmerge.exe to 64 bit installation. Did not help..
