--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This is an expansion bug.

Another ICE can be seen e.g. with
-O2 -fno-tree-forwprop -fno-tree-ccp -fno-tree-fre -fno-tree-pre \
-fno-code-hoisting:
_Complex float
foo (void)
{
  _Complex float c;
  *((unsigned long long *)&c) = 0x123456789abcdef0ULL;
  return c;
}
