Comment (by nbruin):
At least the problem is a real one. I've found a similar iMac:
{{{
Hardware Overview:
Model Name: iMac
Model Identifier: iMac10,1
Processor Name: Intel Core 2 Duo
Processor Speed: 3.06 GHz
Number Of Processors: 1

and `bsd.math.washington.edu`:

Both these machines exhibit the same problem that on 5.4b0 + #715 +
#11521, the doctest for `cachefunc.pyx` segfaults in the same spot.
Note that the iMac claims to not have a 64-bit kernel. Sage is compiled to
be 64-bit on that machine, though (and seems to work).
Have we actually established that this bug does not occur on newer OSX
versions?
