在Windows上用-faddress-sanitizer解压 [英] Clang with -faddress-sanitizer on Windows

问题描述

我的目的是使用 Clang 替换Windows上的 Valgrind ，以找到缓冲区溢出，动态内存滥用等等在我写的C / C ++程序。我已按照此处提供的说明成功构建了Clang。

My intent is to use Clang as a replacement for Valgrind on Windows to find buffer overflows, dynamic memory misuse etc. in C/C++ programs that I've written. I have successfully built Clang following the instructions provided here.

我试图使用-faddress-sanitizer选项编译一个简单的C程序（如指定的

I attempted to compile a simple C program with the -faddress-sanitizer option (as specified here) and the following the error is thrown -

gcc.exe: error: unrecognized command line option '-faddress-sanitizer'
Using built-in specs.
COLLECT_GCC=C:/MinGW/bin/gcc.exe
Target: mingw32
Configured with: ../gcc-4.7.0/configure --enable-languages=c,c++,ada,fortran,objc,obj-      c++ --disable-sjlj-exceptions --with-dwarf2 --enable-shared --enable-libgomp --disable-win32-registry --enable-libstdcxx-debug --disable-build-poststage1-with-cxx --enable-version-specific-runtime-libs --build=mingw32 --prefix=/mingw
Thread model: win32
gcc version 4.7.0 (GCC)
clang: error: assembler (via gcc) command failed with exit code 1 (use -v to see invocation)

$ b b

为什么是clang（我理解它）调用GCC？当然GCC不支持-faddress-sanitizer选项。

Why is clang (as I understand it) invoking GCC? Of course GCC does not support the -faddress-sanitizer option.

我真的很兴奋使用这个，因为我一直在试图找到一个很好的（免费）替代Valgrind一段时间。可以有人请帮忙吗？

I am really excited at the possibility of using this as I've been trying to find a good (free) substitute for Valgrind for a while. Can someone please help?

推荐答案

AddressSanitizer在Windows上工作得更好些（但这仍然是一个工作，进展）。 https://github.com/google/sanitizers/wiki/AddressSanitizerWindowsPort

AddressSanitizer works much better on Windows these days (but it's still a bit of a work-in-progress). There's some documentation at https://github.com/google/sanitizers/wiki/AddressSanitizerWindowsPort
