Backtrace

Steps to reproduce:

1. Mount "RR Kindergarten.iso"

2. Run `wine 'D:\Setup.exe'`

3. Run `WINEDEBUG=+relay wine 'C:\Program Files (x86)\The Learning
Company\Reader Rabbit Kindergarten\rrk32.exe' 2>&1 | tail`

4. Enter and leave areas of the game repeatedly. For example, I tested by
clicking "Dinner Lineup", repairing the stairs, talking to the French raccoon
chef, going back to the main area, then going back to the raccoon chef over and
over.

WINEDEBUG=+relay is not strictly necessary to reproduce the crash, but it makes
it happen much more frequently provided that the output is piped to a program
or to a file other than /dev/null.

A backtrace is attached. It shows an exception in mfc42.dll.

winmm hack for Reader Rabbit Kindergarten

The attached hack prevents the game from crashing. It adds a 2-second delay to
TIME_MMSysTimeCallback in winmm.dll. The 2-second delay also causes the
characters to speak for an extra 2 seconds, repeating in the last 2 seconds of
audio the first 2 seconds of whatever phrase they were speaking.

The 2-second delay has to be after the timer callback is called. Adding a delay
before the callback is called does not prevent a crash. That makes me think
that there is a use-after-free bug either in the game or in MFC. If it's a bug
in the game itself, there's not much that we can do. If it's a bug in MFC, we
might be able to fix it when Wine gets its own MFC implementation (Bug 657).
