Why not use a watchpoint on that location?
Choose some significant function call a while before the crash,
have a breakpoint on that function (a DPA related function probably is best),
check out which infoPtr is the relevant one, then watch on the hdpaItems location, i.e.
watch *0xsomewhere
then continue execution until it triggers and you know where the value got overwritten.

Not me.

In theory it's possible, but valgrind currently doesn't work with Wine any more
(or rather the other way around), AFAIK.
