#5536: Segmentation fault (core dumped) on large file

I am using ffmpeg to compress some big images (about 3500 3000x8000 .tiff
files) and I am using this command:
{{{
ffmpeg -y -framerate 30 -start_number 13244 -i sources/full/full_0%03d.tif
-c:v libx265 -r 30 -x265-params crf=22 -pix_fmt yuv420p
sources/full_brain.mp4
}}}
When I run it on small sets of small images, it works just fine, but on
the big images it crashes after a few frames with messages like
{{{
Segmentation fault (core dumped) 0kB time=00:00:00.00 bitrate=N/A
speed= 0x
}}}
I tried compressing fewer files, but it still segfaults. I don't think
that it is a memory problem, since I have 96 GB of RAM and the same amount
of swap. Also I tried again the command on the smaller sets and it keeps
going just fine.
I am running Ubuntu 14.04.4 LTS (school property, I don't have sudo
privileges) and using the static build.
I have included a log file generated with -report, please tell me if you
need anything else.
Also, I just noticed that H.264 encoding through libx264 does not run into
the problem, still I would need HEVC encoding if possible.
Thank you in advance,
Enrico
