This error is caused by bugs in SWIG 1.3.26/1.3.27, which have not yet
been fixed. I committed a workaround for this bug in r17280. Should we
propose this fix for 1.3.1?

Note the TODO in r17280. (TODO: We should disable this code for new
versions of SWIG, when this SWIG bug is fixed.)

See http://sourceforge.net/mailarchive/forum.php?thread_id=9320590&forum_id=46758
for discussion of this bug on the SWIG list.

Looks like the Ruby bindings need a configure check to add
-fno-strict-aliasing. It might be possible to figure out whether
no-strict-aliasing is needed by looking at the flags which were used
to compile Ruby.

Cheers,
