The abort is about missed optimization - the patch was aiming to fix wrong code issue on dealII and x264. The testcase should work again after https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555927.html where I tracked down the underlying wrong code issue and re-enabled the propagation to inline clones.
