iPhone发布生成内存错误

当我尝试构建我的应用程序的发布版本时，会出现此错误。它会对一个相当大的文件抛出一个错误，但这个文件的大小不接近400+MB（以KBs为单位）

我有3GB的可用ram（6GB中有3GB），CPU容量充足，硬盘上有50GB的可用空间。是什么导致了这个问题

我发现了有关该错误的一些附加信息：

*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

NM，没有看到是cc2obj死了。

如果这是在实际构建过程中，那么我猜你的Mac需要重新启动或重新安装Xcode。编译时不需要那么多RAM，所以它是递归的或类似的。除非gcc有什么问题，否则我怀疑您是否能编写一些代码来导致这种情况。

我已经看到了这一点，它不是一个实际的内存错误

现在的情况是，您的Xcode目标构建设置为release或debug，而“优化级别”的特定设置设置为Fast、faster或faster

似乎有一个错误在那里的某个地方，设置为无，或尝试操作系统，或O3（我不认为最快的是影响）

这很可能会解决一些人遇到的问题。当然，先试试“无”。。。这将证实这是发生在某人身上的事情，看到这一点

我可以肯定地说，McFragma肯定有这个问题，因为他/她描述了从调试到发布的更改，这导致了它（调试已设置为无），而发布设置为其他内容。。。如果是这样的话。。。当然，这是特定的构建设置
