I get a bus error with the following:

I can confirm this, as I was getting the same error today, on pari-gp-2.3.0 during 'make bench'.  My experimentation suggests that the error is caused by a compiler bug in XCode 2.2.1 and earlier, and is resolved by switching to XCode 2.3.

Justin, can you confirm?  Was there a difference in compilers between your two machines?
