heap-buffer-overflow是一个由AddressSanitizer(ASan)检测到的运行时错误,表明程序试图访问堆内存中的一个已分配对象的超出其边界的内存区域。这通常发生在数组访问、字符串操作或指针运算等场景中,当索引或指针偏移量超出了合法范围时。 2. 导致heap-buffer-overflow错误的常见原因 数组越界:访问数组时,使用了
简介Address Sanitizer(ASan)是一个快速的内存错误检测工具。它非常快,只拖慢程序两倍左右(比起Valgrind快多了)。它包括一个编译器instrumentation模块和一个提供malloc()/free()替代项的运行时库。 从gcc 4.8开始,AddressSanitizer成为gcc的一部分。当然,要获得更好的体验,最好使用4.9及以上版本,因为gcc 4.8的Ad.....
其实这是AddressSanitizer 这个工具的内存损坏检查报的错。 可以在Linux上运行如下命令,检查程序是否存在内存非法访问: gcc-O-g-fsanitize=addresstest.c./a.out Linux下运行报错如下: allocatedbythreadT0here:#00x7f8eb21bfd28inmalloc(/usr/lib/x86_64-linux-gnu/libasan.so.3+0xc1d28)#10x563aa79a68bdin...
这个ASan(AddressSanitizer)错误信息表示在你的程序中发生了“heap-buffer-overflow”(堆缓冲区溢出)错误。具体分析如下: 错误详情 错误类型: heap-buffer-overflow:表示对动态分配内存的写操作超出了该内存块的边界。 发生位置: 报错信息显示,程序在地址0xb3600ff8进行了写操作,但这个地址位于一个分配了40字节的内存区...
