For enabling ASan(PE) I collected some "notes to myself", which I hope are enough accurate to enable someone else to reproduce the results.

Thank you for sharing! Goodness, it's a lot more complicated than I had hoped. Notwithstanding the difficulty, following your instructions closely I was able to build and run Wine with the llvm-mingw AUR package.[1] My LLVM variables look like this:
export LLVM_INST_PATH=/opt/llvm-mingw export x86_64_LLVM_CLANG_RT_LIB=$(find $LLVM_INST_PATH -name libclang_rt.asan_dynamic-x86_64.dll.a) export i386_LLVM_CLANG_RT_LIB=$(find $LLVM_INST_PATH -name libclang_rt.asan_dynamic-i386.dll.a)
For my own sanity, I created scripts named configure64.sh, build64.sh, configure32.sh, build32.sh, and run.sh for the various steps of the instructions. I think it would be a lot easier to use your ASan branch if the commands were already in scripts.
Unfortunately I have one patch with LLVM still in progress, therefore a self-built LLVM would be needed, to build wine. But this is just needed for HEAP_REALLOC_IN_PLACE_ONLY re-allocations, and running with "windows_hook_rtl_allocators=0" should not be affected by this, and that way building wine from the plain nightly llvm-mingw package should work.
Could you note that in the README please? Upstream llvm-mingw combined with windows_hook_rtl_allocators=1 resulted in the cryptic error "wine: could not load kernel32.dll, status c0000135" when trying to initialize and use the Wine prefix.
I ran a few parts of the Wine test suite and I've submitted my first patch based on the results.[2] Furthermore, since the instructions in the wiki were outdated and nonfunctional, I've replaced them with a link to your repository.[3] Thanks very much for all the work you put into it!

Hello Alex, thanks for testing and fixing found issues. I missed also in the readme I am using currently a new-style-wow64 configure. Unfortunately I did not get around to put those parts into scripts. However, I rebased to current release and new test runs are in the asan_reports_x86(_64) subdirectories.

Hello, I rebased the current state of the this ASan experiment here [1].
Results of running the conformance tests can be found in [2] [3].
