Question

我为OSX构建了Unity3d应用程序。

但是在内存使用量超过700 mb时应用程序崩溃了一段时间。它存在OSX应用程序的限制内存使用量？我可以收到OSX应用程序的内存警告吗？

崩溃日志：

WWWCurl GetURL时应用程序崩溃。

Answer 1

这是在设备上重现的崩溃：

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

MacBook Pro（Retina，2012年中） OSX 10.10.2 卷曲版本（7.37.1）

将curlib更新到版本7.41后，我无法重现此崩溃。

当使用内存超过700mb时，Unity3d OSX构建崩溃
