Hi @jeroen.dobbelaere, the above two comments of mine are in the wrong order, sorry.

I have attached a C test case, and the problem I'm seeing related to the above comments can be replicated using:

`clang -flegacy-pass-manager -ffull-restrict -fstrict-aliasing -O1 test-verify.c`

F22106280: test-verify.c <https://reviews.llvm.org/F22106280>

The output error I see is on a bitcast instruction:
`This instruction shall not have a TBAA access tag!`

Thanks.
