GCC 4.8 for VAX is generating a subreg:HI for mem:SI indexed address. This
eventually gets caught by an assert in change_address_1. Since the MEM rtx is
SI, legimate_address_p thinks it's fine.
I have a change to vax.md which catches these but it's extremely ugly and I
have to think
I'm looking into http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58901

In handle_aligned_attributes in c-common.c, at line 5146, it does

Then at 5179 it does

TREE_TYPE (decl) = * TREE_TYPE (decl);
or

Over the past several weeks, I've revamped the VAX backend:
- fixed various bugs
- improved 64bit move, add, subtract code.
- added patterns for ffs, bswap16, bswap32, sync_lock_test_and_set,
and
sync_lock_release
- modified it to generate PIC code.
- fixed the dwarf2 output so it is

the VAX uses a single page table of indirection. This greatly reduces
the amount of address space a process can efficiently use. If there
are components that will not be needed by some java programs, it would
nice if they could be separated into their shared libraries.

While taking out fortran and java reduced the disparity, there
