I see this failing on hppa64 as well.

Same here.  When I filed the report, I thought I had seen a codesourcery
build where the test didn't fail.

Confirmed, the size of the struct is too small to cause it to be returned by reference.

See the patch at 
http://gcc.gnu.org/ml/gcc-patches/2006-09/msg00051.html
for a fix.
