------- Comment #10 from rearnsha at gcc dot gnu dot org  2009-05-22 14:51 -------
The ARM7 does not support unaligned accesses in the way that C programmers
normally expect (even if it doesn't fault them in the MMU then it still won't
fetch what you might expect -- see the CPU manuals for details).

As of ARM11 the rules were changed, but that's a different story...
