--- Comment #1 from Martin Liška <marxin at gcc dot gnu.org> ---
Problem is hidden in flag_var_tracking_assignments, which is set to false.
Thus, MAY_HAVE_DEBUG_INSNS is set to false. Unfortunately, Firefox contains
couple of third party libraries that have -g as a default option. So that DCE
after a statements removal does not remove debug statements that use result of
a statement and verifier fails.
