[Martin Storsjö via Phabricator via llvm-commits]

mstorsjo added a comment.

The crash is reproducible with this reduced sample:

  $ cat repro.c 
  struct a { 
    char *b
  } static c; 
  d(());
  e(struct a *f) { d(f->b); }
  g() { 
    while (h())
      e(&c);
  }
  $ clang -target x86_64-linux-gnu -c -g -O2 repro.c
