[tmodes <717944@xxxxxxxxxxxxxxxxxx>]

The problem is memory usage and number of threads (aka cores).
Looking at the inital report it tries to load and remap 8 images at one time. This steps needs propably "too much" memory.
So we need to reduce memory usage or/and automatically restrict the number of threads depending on image sizes.

Workaround could be to limit the number of threads with command line
option --ncores.

Title:
  cpfind memory allocation error

Status in Hugin - Panorama Tools GUI:
  Confirmed

Bug description:
  On running cpfind with 12 16-bit TIFF files, each 5616x3744, cpfind is
  crashing as follows.   Perhaps it should have an option to downsample
  further or do so automatically.   I'm running on a mac with 32GBytes
  of RAM.
