Watch point for unaligned stores

I had a bug where the word at 0x8 was being clobbered by some bug in
my program. I set at a watchpoint (watch *(int*)8) but it was never
triggered even though the memory was modified. I found in the end that
the errant instruction was writing a word at address 0x9, which on the
ARM architecture modifies the word at 0x8 due to alignment. Could I
set a watchpoint that would have caught this bug, other than say
setting a watchpoint at all four addresses of the word?
Thanks,
Shaun
