--- Comment #9 from Andrew Pinski <pinskia at gcc dot gnu.org> --- One more thing, you can without setting STAGE1_* options to make sure that stage1 is not miscompiled in the first place? With STAGE1_* env set it could be stage1 is being miscompiled which is causing stage 2 to be even more miscompiled. This is why the default options for stage1 is `-O0`. Yes it will be slower but at least we know that it is an issue with GCC 14 rather than the previous compiler.
