ok, what did you do to reproduce this problem?

Comment 2

[timeless]

i ran mfcembed, i attached w/ a debugger, i asked it to quit (it deadlocked
because postmessage fails somehow)
i ran mfcembed a couple of more times and each of them suffered from this (i had
not killed ipcd)
i got this annoying assertion dialog and eventually traced enough to see where
it came from
