@@ -187,7 +187,7 @@ Please note, however, the following caveats!
 
 * ASAN will not work properly on any currently released version of Ruby; the necessary support is currently only present on Ruby's master branch.
 * Due to [this bug](https://bugs.ruby-lang.org/issues/20243), Clang generates code for threadlocal variables which doesn't work with M:N threading. Thus, it's necessary to disable M:N threading support at build time for now.
-* Currently, ASAN will only work correctly when using a recent head build of LLVM/Clang - it requires [this bugfix](https://github.com/llvm/llvm-project/pull/75290) related to multithreaded `fork`, which is not yet in any released version. See [here](https://llvm.org/docs/CMake.html) for instructions on how to build LLVM/Clang from source (note you will need at least the `clang` and `copmiler-rt` projects enabled). Then, you will need to replace `CC=clang` in the instructions with an explicit path to your built Clang binary.

 * ASAN has only been tested so far with Clang on Linux. It may or may not work with other compilers or on other platforms - please file an issue on [https://bugs.ruby-lang.org](https://bugs.ruby-lang.org) if you run into problems with such configurations (or, to report that they actually work properly!)
 * In particular, although I have not yet tried it, I have reason to believe ASAN will _not_ work properly on macOS yet - the fix for the multithreaded fork issue was actually reverted for macOS (see [here](https://github.com/llvm/llvm-project/commit/2a03854e4ce9bb1bcd79a211063bc63c4657f92c)). Please open an issue on [https://bugs.ruby-lang.org](https://bugs.ruby-lang.org) if this is a problem for you.
