--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Started with r216305.  As expected, -fno-ipa-icf fixes this.
For GCC 5.x and maybe even for GCC 6.x, best would be probably just to disable
ICF for functions with constructor/destructor argument, and for stage1 add
wrappers for these.
