Bug ID: 30693
           Summary: AVX512 Segfault: alignment incorrect for relative
           Product: new-bugs
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: new bugs
    Classification: Unclassified

Steps to reproduce:
git clone -b clang
cd gromacs
mkdir build
cd build
FLAGS=-g; CFLAGS=$FLAGS CXXFLAGS=$FLAGS CC=clang CXX=clang++ cmake .. -GNinja
ninja mdrun-test

It segfaults on
0x00000000009f4622 <+370>:   vmovdqa 0x5b6fa(%rip),%xmm7        # 0xa4fd2

That relative address is not aligned to 16 and thus segfaults.

Sorry I have no idea how to produce a small test case for this.
