Sorry that I failed to find this before, but this looks very much like a duplicate of #4817. The valgrind output is basically identical.
But #4817 also segfaults on commit 76c1f9200fa3bf16a47042c0c2a1bd11e408b56c where my example does not segfault. (which is the commit preceeding 4818388e6c219bf48fa93bf76ee6ab3dc3fb1e8f)
I will close this ticket as duplicate, and when #4817 is fixed, I will validate if it also fixes my example. (but feel free to reopen if you don't agree)
