Wow nice, I didn't know about this one. I can add some more which are less known. This is my current sanitize invocation (minus the addition of "integer" which I'll be adding, unless one of these other ones covers it):

  -fsanitize=address,leak,undefined,cfi,function

CFI has checks for unrelated casts and mismatched vtables which is very useful. It requires that you pass -flto or -flto=thin and -fvisibility=hidden.

You can read a comparison with -fsanitize=function here:

https://clang.llvm.org/docs/ControlFlowIntegrity.html#fsanit...

There's also TypeSanitizer, which isn't officially released, but is really interesting and should be able to be applied via a patch from the branch:

  $ curl -L 'https://reviews.llvm.org/D32199?download=1' | patch -p1

I think "leak" is always enabled by "address". It's only useful if you want run LeakSanitizer in stand-alone mode.

Ah I wasn't sure if LSAN was always enabled with ASAN, good to know -- ty!
