--- Comment #6 from Martin Jambor <jamborm at gcc dot gnu.org> --- (In reply to Sam James from comment #3) > Martin, do you think your PR123542 fix handles this? But then why doesn't it > abort properly instead (it's a checking build)? I'd be a bit surprised, because it is the backtrace in comment #2 is about the ipa_polymorphic_call_context overload of the function decide_about_value. But as I wrote in the other bug, https://gcc.gnu.org/pipermail/gcc-patches/2025-December/702974.html could help (though I was only able to see that problem with extreme IPA-CP parameters).
