使用工具检测内存错误:如AddressSanitizer(ASan),它可以在运行时自动检测许多内存访问错误,包括heap-buffer-overflow。 具体的代码示例 以下是一个简单的C++代码示例,展示了如何避免heap-buffer-overflow错误: cpp #include <iostream> #include <cstring> int main() { const char* source = "Hello,...

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...

FYI - the cmake build now support building with ASAN, like this. cmake -S . -B build -D MZ_BUILD_TESTS=ON -DMZ_SANITIZER=Address When I run that I get the line numbers where the problems are ./minizip -x poc0 minizip-ng 4.0.2 - https://github.com/zlib-ng/minizip-ng ...
