It seems to be the case, see Misc/README.AIX.  This could explain the
MemoryErrors, but not the segfaults.


Are computed-gotos stable on gcc-AIX?  The README recommends disabling
them for xlc.


I'm also not sure how well Python supports threads on AIX. Often
these problems go away on unsupported platforms when configuring
--without-threads.
