> It's a known fallout..
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.
