--- Comment #13 from Tom de Vries <vries at gcc dot gnu.org> ---
I've tried to see if I could workaround the problem by disabling the assert:
...

That worked for pr66714.c, but for all other ICE-ing test-cases I run into
another ICE, now in mkoffload:
...
else
{
/* Pickle stray references. */
t = lto_input_tree_1 (&ib_main, data_in, tag, 0);
gcc_assert (t && data_in->reader_cache->nodes.length () == from);
}
