[PATCH] D124571: Avoid strict aliasing violation on type punning inside llvm::PointerIntPair

[Breno Rodrigues Guimaraes via Phabricator via llvm-commits]

brenoguim added a comment.

I created a compiler explorer example without PointerIntPair to show the core of the issue: https://godbolt.org/z/xvofbdYP8
I also added options in this example to use memcpy for reading the pointer and show that it solves the issue. I added an option to show that using "char" as underlying storage is not enough to solve the issue, though I still think it may be the correct thing to do.
