GC对未注册线程的操作 [英] GC Operation on unregistered thread

问题描述

我在我的应用程序中的OS X Lion 10.7得到以下错误。我已经查明是什么原因造成的错误，但要找出如果这是在10.7或出现错误已经改变了，我很想念。

I am getting the following error on OS X Lion 10.7 in my application. I have pinpointed what is causing the error, but want to find out if this is a bug in 10.7 or if something has changed that I am missing.

malloc: *** auto malloc[3677]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug.

运行 bt 时GDB的堆栈跟踪在断点：

The stack trace from GDB when running bt on the breakpoint:

导致Garbage Collection线程错误的代码是：

The code that is causing this Garbage Collection thread error is:

NSSound *completedSound = [NSSound soundNamed:@"Glass"];
[completedSound play] //this line is causing the error;

所有行都是播放在系统上注册的系统声音之一，由用户。

All that line does is play one of the system sounds that are registered on the system as selected by the user. To me it seems like a bug, and I have filed a bug report just in case.

任何人都体会到了这一点？

Anybody else experienced this?

推荐答案

我看到相同的消息，语音合成器停止。

I see the same message with the speech synthesizer stopping.
