--- Comment #7 from Mikhail Maltsev <miyuki at gcc dot gnu.org> ---
Yes, it helps. Also consider adding this testcase to g++.dg (used to ICE on
x86_64):

// PR rtl-optimization/68392
// { dg-do compile }
// { dg-options "-O -fno-checking" }

void tool_cleanup(bool from_signal)
{
  tool_cleanup(from_signal);
}
