guardmalloc什么是那些警告，我如何摆脱他们？ [英] guardmalloc what are those warnings and how do I get rid of them?

问题描述

GuardMalloc：分配将放置在16字节边界。
GuardMalloc： - 某些缓冲区溢出可能不会被注意到。
GuardMalloc： - 使用向量指令的应用程序（例如，SSE或Altivec）应该工作。
GuardMalloc：GuardMalloc version 18
（gdb）

所有突然的那些guardmalloc消息出现在控制台窗口中。原因是什么，如何摆脱它？

解决方案

我想你有意启用GuardMalloc来查找内存错误？如果是这样，这些只是因为正在使用GuardMalloc（如 http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man3/guardmalloc.3.html ）。

behaves weird是什么意思？出现什么症状？

GuardMalloc: Allocations will be placed on 16 byte boundaries. GuardMalloc: - Some buffer overruns may not be noticed. GuardMalloc: - Applications using vector instructions (e.g., SSE or Altivec) should work. GuardMalloc: GuardMalloc version 18 (gdb)

all of the sudden those guardmalloc messages appears in the console window. What's the cause and how do I get rid of it? Mostly because the application behaves weird after those appear.

解决方案

I guess you have intentionally enabled GuardMalloc to find memory errors? If so, these appear simply because GuardMalloc is being used (as shown by http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man3/guardmalloc.3.html ).

What do you mean by "behaves weird"? What symptoms appear?
