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.
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)
Why is clang (as I understand it) invoking GCC? Of course GCC does not support the -faddress-sanitizer option.
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?
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
Googling brought me to this page.
To quote,
AddressSanitizer is supported on
- Linux x86_64 (tested on Ubuntu 10.04).
- MacOS 10.6 and 10.7 (i386/x86_64).
Support for Linux i386/ARM is in progress (it may work, but is not guaranteed too).
On the topic of replacement, have you looked at Dr. Memory?
