Unity3d OSX在使用内存超过700MB时会崩溃

问题描述：

我为OSX构建Unity3d应用程序。Unity3d OSX在使用内存超过700MB时会崩溃

但在某些时候应用程序崩溃时，内存使用量超过700 MB。 OSX应用程序存在限制内存使用情况吗？我可以收到有关OSX应用程序的内存警告吗？

应用程序崩溃WWWCurl的GetURL时。

崩溃日志清楚地指出，在调用Signal函数时，一个对象被释放了两次，显然在你的'PlatformSemaphore'类中。你没有耗尽内存。 – JustSid 2015-04-01 17:23:40

这是崩溃转载的设备：

MacBookAir的6,2 OSX 10.10.2 卷曲版本（7.37.1）

的MacBook Pro（视网膜，2012年中） OSX 10.10.2 curl版本（7.37.1）

将curlib更新到版本7.41后无法重现此崩溃。
