我编码一个游戏的Mac在C++中,我得到一个SIGABRT和控制台打印如下:的Mac:我得到SIGABRT但调用堆栈是没用

terminate called after throwing an instance of 'boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::bad_lexical_cast> >' 
    what(): bad lexical cast: source type value could not be interpreted as target 
Program received signal: “SIGABRT”. 

所以,我做一个糟糕的lexical_cast。但问题是我不知道在哪里,因为调用堆栈如下:

#0 0x7fff85fb629a in mach_msg_trap 
#1 0x7fff85fb690d in mach_msg 
#2 0x7fff81f58932 in __CFRunLoopRun 
#3 0x7fff81f57dbf in CFRunLoopRunSpecific 
#4 0x7fff88dba7ee in RunCurrentEventLoopInMode 
#5 0x7fff88dba5f3 in ReceiveNextEventCommon 
#6 0x7fff88dba4ac in BlockUntilNextEventMatchingListInMode 
#7 0x7fff84f85e64 in _DPSNextEvent 
#8 0x7fff84f857a9 in -[NSApplication nextEventMatchingMask:untilDate:inMode:dequeue:] 
#9 0x7fff84f4b48b in -[NSApplication run] 
#10 0x7fff84f441a8 in NSApplicationMain 
#11 0x1000ef759 in os_gameMainLoop at main-osx.mm:22 
#12 0x10009a97d in main at words.cpp:18 

这不是正确的堆栈。

什么是match_msg_trap?
我能接到这个调用堆栈吗?
我有什么方法可以在崩溃时获得良好的调用堆栈吗?

谢谢!

调试器停在错误的线程中。在GDB中尝试t a a bt以查看所有线程的回溯。

​​是线程在等待消息进入时驻留的地方。因此,您正在查看未运行的线程。 Mach是OS X上消息传递接口的名称。

非常感谢!这是问题所在 – Damian 2011-04-08 11:14:05
