Comment (by rwbarton):

 I see. There are two patches to aeson there, one to relax the version
 bound on attoparsec and one to add whatever functionality is missing in
 the old version. I tried building all these versions together with these
 patches applied (on a Linux machine) and they built successfully and
 unsurprisingly did not segfault when I tried your example. I didn't check
 whether any other packages among these had patches in ports.

 I wonder if the segfault would go away if you just rebuilt all the
 libraries...
