[Yuv <717944@xxxxxxxxxxxxxxxxxx>]

I can now confirm that what I saw in comment #3 is not related to this
thread.  My error was due to an image being in the wrong format.  It
also caused bug 779563.  I will file e separate ticket for that. Apology
for the thread hijack.

Agree that manually limiting the number of cores should not be
necessary.  The problem will affect an increasing number of users in the
future.

The solution is some logic before spawning the thread.  Spawn it only if
enough memory can be allocated.

Question: memory = physical RAM?  or memory = available memory including
(slow) swap?

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.
