Hello everyone,
I am debugging a problem for some of my 10.2.8 users. The problem
appears to be that playing sounds via NSSound sometimes results in a
crash. The crash occurs in QuickTime, as on 10.2.8 QuickTime is used
to play sounds. (10.3 prefers to use CoreAudio for playing sounds...
and appears to be rock solid compatatively.) My sounds are all short
AIFF sounds.
The crash is always pretty consistent. It looks like this:
Thread 0 Crashed:
#0 0x91a52e00 in GetEffectiveFrameBufferPixmap

#14 0x9315fc58 in NSApplicationMain
#15 0x0000a05c in _start (crt.c:267)
#16 0x00009edc in start
There are some interesting things you can see by looking at this stack
crawl. For example, TaskMovie_priv is attempting to do some things
with QuickDraw. Of course, I have no idea what port it could would be
using as it's up to NSSound to deal with that.
Has anyone run into this problem before? Any suggestions?
thanks,
Chris
