I note that the CSW GCC 4.6.3 I'm using on SPARC also produces warnings
when building mdb with -Wcast-align.


Rebuilt with the Sun compilers to get proper debug info, the faulting
instruction is the same as the one in GCC:

signal SEGV (no mapping at the fault address) in mdb_env_pick_meta at line 3349 in file "mdb.c"
3349           return (env->me_metas[0]->mm_txnid < env->me_metas[1]->mm_txnid);

I don't have MIPS specsheets memorized/in front of me, but what's the pagesize?
