If this is a system that supports hardware watchpoints (like Linux on
x86), then you should be able to do a "watch VfdCache[0].fd". In
fact, if you know the specific value it's going to be set to, you can
do a conditional watchpoint: "watch VfdCache[0].fd if VfdCache[0] ==
<value>" (you can set the condition to be pretty much anything).
The program will stop on the statement immediately following the one
that scribbled on the area you're watching when the condition you
specify is met. Note, though, that the condition is tested *after*
the modification happens.
