System Information
64bit Manjaro Linux, kernel 3.14.29
CPU: AMD Phenom II 970 Deneb quad-core
GPU: nVidia GTX 650 Ti, driver 343.36

Blender Version
Broken: 2.73 devel, hash 59e2f91

Short description of error
This particular scene exhibits crashes whenever the feathers use a material containing some nebulous combination of non-diffuse shader nodes. In this particular case, a mix node with transmission and reflective Hair BSDF nodes.

When using one of the latest builds off of buildbot, this crash occurs only when rendering in CPU mode. GPU mode works just fine. The 2.73 release version behaves differently, however (and 2.73a as well, most likely). CPU mode takes an obscene amount of time to render tiles containing ParticleSystem1 on the wing arms (8:15 minutes with the particle system enabled, 12 seconds with it disabled), while GPU mode freezes the GPU itself upon switching to the 2nd tile, requiring a reboot.

Above, I note that the 2.73 release version "sort of" works. By that, I mean instead of crashing, it takes an obscene amount of time to render tiles containing hairs from a specific particle system on the wing "arms". Total render time is 8:15 minutes, and disabling the trouble particle system (ParticleSystem1 on the arms) reduces the render time to 12 seconds.

Last paragraph before the repro steps should be ignored, forgot to delete it after rewriting the description.

Latest master on release builds works OK here and even faster than 2.73 but debug builds get an abort signal from operating system...not sure what to do with this. @Sergey will know what to do here

In case it's useful, here is the command line output I received during the crash:

Stepped out of update shape due to exception.
write exr tmp file, 512x512, /tmp/blender_Uq1lKF/WingRigging_r8_blend_Scene_RenderLayer_exr
Writing: /tmp/WingRigging r8.crash.txt
Segmentation fault

The specified crash log is empty.
