Memory leaks (experimental) 使用clang编译代码时用-fsanitize=address就能打开AddressSanitizer工具,为了在检测到内存错误时打印出您的程序调用栈,需要在编译时加上选项 -fno-omit-frame-pointer选项,同时为了得出更清晰的调用栈信息,请用-O1选项编译程序。 4 示例代码 下面我用clang3.4做一个示例 1: int main()2:...
我想使用DS-5 Streamline profiler来分析我的代码。在它提到的文档中,为了能够看到调用堆栈,我们需要使用编译器选项-fno-omit-frame-pointer编译代码。gcc也有这样的选择。对clang也有同样的选择吗? -fno-omit-frame-pointer不是在为我工作。 我还尝试将编译器优化级别设置为0,但仍然没有得到流线型调用堆栈。 streamli...

Based on the reasoning in https://fedoraproject.org/wiki/Changes/fno-omit-frame-pointer, I propose adding these two flags to the default (and do so for GCC in the respective feedstock). As far as my understanding goes, this should not change the ABI and individual packages are free to ...
We recompiled our NDK, adding -fsanitize=address -fno-omit-frame-pointer to LOCAL_CFLAGS and -fsanitize=address to LOCAL_LDFLAGS. Running the app on AVD then showed any memory issues as stack traces inside Logcat and helped a lot with finding memory leaks. The only remaining issue was ...
