--- Comment #4 from Martin Liška <marxin at gcc dot gnu.org> ---
I can't reduce it more, so it's hopefully a reasonable small test-case:

$ g++ 1.ii 2.ii 3.ii 4.ii -O3 -flto=auto -shared -fPIC
...
1.ii:42:572: note: code may be misoptimized unless ‘-fno-strict-aliasing’ is
used
during IPA pass: materialize-all-clones
In function ‘throwError.constprop.isra’:
