Comment:

 I updated Numpy to the Git version:

 numpy.__version__
 '1.7.0.dev-Unknown'

 And the problem persists. I attach the new backtrace. I'll try to create a
 "short" code to reproduce the problem, independent from the data.
 Meanwhile, I try to help describing what it does:

 - Load 45 arrays, of 4600x3840, from netcdf files.
 - Plot 15 RGB images, composed by 3 arrays each, on the same figure.

 I think it is a memory related issue, as it eats all my RAM and swap, but
 I was expecting a Memory Exception instead of a Segfault. If I plot
 grayscale images instead of RGB, so loading just 15 arrays (one per
 image), it works OK.

 BTW, my system is:
 Arch Linux
 Linux mirto 3.3.4-2-ARCH #1 SMP PREEMPT Wed May 2 18:28:42 CEST 2012
 x86_64 Intel(R) Core(TM) i5-2500 CPU @ 3.30GHz GenuineIntel GNU/Linux
 4 GB RAM, 4GB swap
