Thanks a lot for the fix.

"struct upcall" is a large data structure (almost 2 kB on x86-32), so
this one-line fix is going to be very expensive.  To avoid a performance
regression, I suggest using an assignment statement rather than an
initializer, which necessarily initializes the entire structure.

Would you mind respinning it that way?
